RF Technology R220 Page 51 OPERATING INSTRUCTIONSWARNINGChanges or modifications not expressly approvedby RF Technology could void your authority tooperate this equipment. Specifications may varyfrom those given in this document in accordancewith requirements of local authorities. RFTechnology equipment is subject to continualimprovement and RF Technology reserves the rightto change performance and specification withoutfurther notice.1 Operating Instructions1.1 Front Panel Controls and Indicators1.1.1 Mon. VolumeThe Mon. Volume control is used to adjust the volume of the internal loudspeakerand any external speaker connected to the test socket. It does not effect the level ofthe 600Ω line or direct audio output.1.1.2 Mon. SQ.The Mon. SQ. switch allows all squelch functions controlling the monitor output tobe disabled. When the switch is in the Mon. SQ. position the audio at the monitorspeaker is controlled by the noise detector. The CTCSS, carrier and external squelchfunctions are disabled. This can be useful when you are trying to trace the source ofon-channel interference or when setting the noise squelch threshold. the audio fromthe 600Ω line and direct outputs is not effected by the switch position.1.1.3 N.SQThe N.SQ trimpot is used to set the noise squelch sensitivity. Use the followingprocedure to set the noise squelch to maximum sensitivity.1. Set the toggle switch to the Mon. Sq. position and set the Mon. Volume controlto 9 o’clock.
Page 6 RF Technology R2201.1 Front Panel Controls and Indicators 1.1 OPERATING INSTRUCTIONS2. Turn the N. SQ. adjustment counter clockwise until the squelch opens andnoise is heard from the speaker. Adjust the VOLUME to a comfortablelistening level.3. In the absence of any on channel signal, turn the N.SQ. screw clockwise untilthe noise in the speaker is muted. Then turn the screw two additional turns inthe clockwise direction.1.1.4 C.SQThe C.SQ trimpot is used to set the carrier squelch sensitivity. Carrier squelch isuseful at higher signal levels than those at which noise squelch and can be usedtypically from 1-200µ V input.It is provided mainly for use in fixed link applications where a high minimum signalto noise ratio is required or where very fast squelch operation is required for datatransmission. The carrier squelch will open and close in less than 2 mSec.In most base station applications carrier squelch is disabled by turning the adjustmentcounter clockwise until the screw clicks.The carrier squelch may be set to a predetermined level with the Techelp/ServiceMonitor 2000 software or by using the following procedure:1. First turn the adjustment fully counter-clockwise. Then set the noisesquelch as above.2. Connect a source of an on channel signal with the desired threshold level tothe receiver's RF input.3. Turn the screw clockwise until the SQ LED goes OFF. Then turn the screwback until the LED just comes ON.1.1.5 LINEThe LINE trimpot is used to set the line and direct audio output level. It is normallyset to give 0dBm (775mV) to line with a standard input signal equal to 60% ofmaximum deviation at 1 KHz. The level can be measured between test socket pins 6and 1 and set as desired.1.1.6 PWR LEDThe PWR LED shows that the dc supply is connected to the receiver.1.1.7 SQ LEDThe SQ LED comes on when the audio to the line and direct outputs is un-squelched.

Page 12 RF Technology R2204 FREQUENCY PROGRAMMING4 Frequency ProgrammingChannel and tone frequency programming is most easily accomplished with RFTechnology TecHelp/Service Monitor 2000 software. This software can be run onan IBM compatible/Windows PC and provides a number of additional usefulfacilities.TecHelp/Service Monitor 2000 allows setting of the adaptive noise squelchthreshold, provides a simple means of calibrating the signal strength output andminimum signal alarm.TecHelp/Service Monitor 2000 can be supplied by your dealer, distributor or bycontacting RF Technology direct.5 Circuit DescriptionThe following descriptions should be read as an aid to understanding the block andschematic diagrams at the rear of this manual.5.1 RF SectionA two pole voltage tuned filter (D13, D14, L35-39) is used to limit the RF bandwidth prior to the RF amplifier transistor Q1. The tuning voltage is supplied by thefrequency synthesizer through voltage follower U28D. The circuit values are chosenso that the centre frequency tracks the VCO frequency.RF amplifier transistor Q1 is followed by a second two pole voltage tuned filter(D15, D16, L28-32) which provides additional image and spurious frequencyrejection. The filter output is connected to the RF input port of the mixer MX1.MX1 is a high level double balanced diode ring mixer with excellent intermodulationperformance. It has a conversation loss of approximately 6 dB. The gain betweenthe receiver input and the mixer input is approximately 10 dB so that the total gainbetween the antenna input and the IF input 3-4dB.Monolithic amplifiers MA1, MA2 and transistor Q5 amplify the VCO output to thenecessary LO level for MX1 approximately +13dBm.The network C8, C9 L1-3 and R6 passes the IF frequency of 45 MHz and terminatesthe RF and LO components.5.2 IF SectionThe first IF amplifier uses two parallel connected JFET transistors Q2 and Q3 toobtain 8-10 dB gain. The two transistors provide improved dynamic range and inputmatching over a single transistor.
RF Technology R220 Page 135 CIRCUIT DESCRIPTION 5.2 IF SectionA two pole 45 MHz crystal filter XF1 is used between the first and second IFamplifiers. The second IF amplifier Q4 provides additional gain of 6-10dB. A twopole crystal filter is used between Q4 and the 2nd oscillator mixer. These two crystalfilters provide some adjacent channel rejection and all of the second IF imagefrequency rejection.U1 is a monolithic oscillator and mixer IC. It converts the 45 MHz IF signal down to455 KHz. The second oscillator frequency or 45.455 MHz is controlled by crystalY1. The 455 KHz output of the second mixer is fed through a ceramic filter CF1 tothe second IF amplifier transistor Q27. Q27 provides an additional 15 dB gain aheadof the limiter and discriminator IC U3.The limiter/discriminator IC U3 further amplifies the signal and passes it throughCF2. CF2 does not contribute to the adjacent channel rejection but is used to reducethe wide band noise input to the limiter section of U3.The limiter section of U3 drives the quadrature detector discriminator. C31 and IFtuned circuit L10 comprise the discriminator phase shift network.U3 also has a received signal strength indicator output (RSSI). The RSSI voltageconnects to the test socket for alignment use. The RSSI voltage is also used by themicroprocessor for the adaptive noise squelch, carrier squelch and low signal alarmfunctions.Dual op-amp U2 is used to amplify and buffer the discriminator audio and RSSIoutputs.5.3 VCO SectionThe Voltage Controlled Oscillator uses a junction FET Q6 which oscillates at therequired mixer injection frequency. Varactor diode D4 is used by the PLL circuit tokeep the oscillator on the desired frequency. Transistor Q7 is used as a filter toreduce the noise on the oscillator supply voltage.5.4 PLL SectionThe synthesizer frequency reference is supplied by a temperature compensatedcrystal oscillator (XO1). The frequency stability of the oscillator is better than 1ppm.The 12 MHz output of Q25 or XO1 is amplified by Q8 to drive the reference inputof the PLL synthesizer IC U4. This IC is a single chip synthesizer which includes a1.1 GHz pre-scaler, programmable divider, reference divider and phase/frequencydetector. The frequency data is entered a serial data link from the microprocessor.The phase detector output signals of U4 are used to control two switched currentsources. The output of the positive and negative sources' Q10 and Q16, produce thetuning voltage which is smoothed by the loop filter components to bias the VCOvaractor diode D4.
Page 14 RF Technology R2205.5 Audio Signal Processing 5 CIRCUIT DESCRIPTION5.5 Audio Signal ProcessingA 4 KHz low pass filter (U27b) is used to remove high frequency noise from thesignal. A 300 Hz high pass filter (U26a,b) then removes the sub-audible tones. A 240Hz notch filter (U26c,d) is used to improve the rejection of tones above 200 Hz. Thehigh pass and notch filters can be bypassed by internal jumpers JP1 and JP3.The audio frequency response can be set for either 750 uS de-emphasis or a flatcharacteristic by JP2. JP2 selects the feedback network of amplifier U27c.After de-emphasis and filtering, the audio signal is applied to the inputs of twoanalog switches (U17a,b). These switches are controlled by the micro-controller andsquelch or mute the audio to the line and monitor output circuits. The monitor outputcan be set for noise squelch only operation by S1.The audio from U17a is adjusted by the volume control before connecting to themonitor output amplifier U5. U5 drives the internal speaker and can also supply 3-5watts to an external loudspeaker.The audio from U17b is adjusted by RV3 before connecting to the line output IC(U22a,b). U22 is a dual amplifier connected in a bridge configuration to drive the600Ω line output transformer T1.5.6 Noise Filter, Amplifier and DetectorThe unfiltered audio from the discriminator is fed to trimpot RV4 which is used toset the noise squelch threshold. From RV4 the audio goes to the noise filter (U27a).This is a 10 KHz high pass filter and is used to eliminate voice frequencycomponents.The noise signal is then amplified by U27d and fed to the noise detector. The noisedetector consists of D6, Q17 and U26c. D6 and Q17 are a charge pump detector andpull the input to U26c low as the noise increases. U26c has positive feedback andacts like a schmitt trigger. The output of U26c goes high when noise is detected. Itconnects to the micro-controller and to analog switch U17d. U17d varies the gain ofthe noise amplifier to provide approximately 2dB hysteressis.5.7 Sub-Tone Filter and CTCSSThe discriminator audio is fed through cascaded low pass filters U28a and U28b tofilter out the voice frequency components. The filtered sub-tone audio is supplied tothe CTCSS hybrid and the rear panel system connector. The filtered output can beused for re-transmission of CTCSS or DCS.The CTCSS decoder module is a micro-controller base hybrid module. Under controlof the main microprocessor U15 it can decode all 38 EIA tones and 12 additionalcommonly used tones. The decode bandwidth is set to 1% but may be changed to 2%by a jumper on the printed circuit board.
RF Technology R220 Page 155 CIRCUIT DESCRIPTION 5.8 External Squelch5.8 External SquelchThe audio output can be muted through pin 8 of the receiver system connector P1.When pin 8 is pulled to less than 1 volt above ground, the micro-controller U15 willmute the audio output.This facility can be used to mute the audio during transmission, as is required insingle frequency systems, by simply connecting pin 8 of the receiver to thetransmitter T/R relay driver output (pin 16 on Eclipse transmitters).5.9 Microprocessor ControllerThe microprocessor controller circuit uses an advanced eight bit processor andseveral support chips. The processor U15 includes EE memory for channelfrequencies, tones, and other information. It also has an asynchronous serial port andan analog to digital converter.The program is stored in U12, a CMOS EPROM. U13 is an address latch for the loworder address bits. U11 is used to read the channel select lines onto the data bus. U7is an address decoder for U11 and U12. U14 is a supervisory chip which keeps theprocessor reset unless the +5 Volt supply is within operating limits. U16 translatesthe asynchronous serial port data to standard RS232 levels.The analog to digital converter is used to measure the received signal strength, tuningvoltage, dc supply voltage and the carrier squelch setting.5.10 Carrier Operated SwitchThe carrier operated switch is an opto-coupled (ISO1) output. Internal jumpers(JP4,7,8,9) can be connected to provide loop source, loop switch, free switch andvarious other configurations.The COS can be set to be active (switch closed) on carrier or active in the absence ofcarrier.The generic term ``Carrier Operated Switch'' may be misleading in this case. SINCE,if a sub-audible tone has been programmed for the channel in use, the COS iscontrolled by carrier and tone detection.
Page 16 RF Technology R2205.11 Voltage Regulator 5 CIRCUIT DESCRIPTION5.11 Voltage RegulatorThe dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. Theseries pass transistor Q20 is driven by error amplifiers Q21 and Q22. Q23 is used tostart up the regulator and once the circuit turns on, it plays no further part in theoperation.This circuit is short circuit and overload protected. It provides much better lineisolation and lower dropout voltage than can be obtained with current integratedcircuit regulators.6 Alignment ProcedureThe following procedures may be used to align the receiver for optimumperformance. Normally only RF alignment will be required when changingfrequencies. IF alignment should only be necessary after repairs on that part of thecircuit.Reference oscillator or TCXO calibration may be required periodically due to crystalaging. The aging should be less than 1 ppm/year.6.1 Standard Input SignalRF Signal Generator50Ω output impedanceFrequency range 215 - 240 MHzFM modulation at 1KHz1.5KHz peak for 12.5KHz channel spacing6.2 RF AlignmentAlignment Frequency215 - 240 MHz range 221.000 MHz

This is to provide the capability of programming allchannels into all of the receivers used at a given site.7.1.2 CTCSSThe CTCSS tone or no tone can also be programmed for each channel. So that eachchannel number can represent unique RF and tone frequency combination.7.1.3 Channel ProgrammingThe channelling information is stored in a non-volatile memory chip and can beprogrammed via the front panel test connector using a PC and RF Technologysupplied TecHelp/Service Monitor 2000 software.
RF Technology R220 Page 197 SPECIFICATIONS 7.1.4 Channel Selection7.1.4 Channel SelectionChannel selection is by eight channel select lines. These are available through therear panel connector.A BCD active high code applied to the lines selects the required channel.
