RF Technology T350/T500Page 51OPERATING INSTRUCTIONS1Operating Instructions1.1 Front Panel Controls and Indicators1.1.1 PTTA front-panel push-to-talk (PTT) button is provided to facilitate bench and field testsand adjustments. The button is a momentary action type. When keyed, audio from theline input is disabled so that a carrier with sub-tone is transmitted. The front-panelmicrophone input is not enabled in this mode, but it is enabled when the PTT line onthat socket is pulled to ground.1.1.2 LineThe LINE trimpot is accessible by means of a small screwdriver from the front panel ofthe module. It is used to set the correct sensitivity of the line and direct audio inputs. Itis factory preset to give 60% of rated deviation with an input of 0dBm (1mW on 600Ωequivalent to 775mV RMS or about 2.2V peak-to-peak) at 1kHz. The nominal 60%deviation level may be adjusted by measuring between pins 6 and 1 on the test socket,and adjusting the pot. By this means an input sensitivity from approximately -30dBm to+10dBm may be established.An internal jumper provides a coarse adjustment step of 20dB. Between the jumper andthe trimpot, a wide range of input levels may be accommodated.WARNINGChanges or modifications not expressly approved byRF Technology could void your authority to operate thisequipment.

A varactor diode is used by the PLL circuit to keep theoscillator on the desired frequency. Transistor Q20 is used as an active filter to reducethe noise on the oscillator supply voltage. The VCO is keyed ON by themicrocontroller through Q10. It is keyed ON when any of the PTT inputs are active andOFF at all other times.
Page 10 RF Technology T350/T500 5 CIRCUIT DESCRIPTION The VCO output is amplified and buffered by monolithic amplifiers MA2 and MA3before being fed to the PLL IC U6.Amplifiers MA1, MA4 and MA5 increase the VCO output to approximately 4 mW todrive the power amplifier. MA1 is not switched on until the PLL has locked and hadtime to settle. This prevents any momentary off channel transmission when thetransmitter is keyed.5.2 PLL SectionTemperature compensated crystal oscillator XO1 is the frequency reference source forthe PLL Synthesizer. The frequency stability of XO1 is better than 1 ppm and it can besynchronized to an external reference for improved stability. External reference optionboard 11/9119 is required when using an external reference.XO1 is frequency modulated by the processed transmit audio signal from U7b. Thisextends the modulation capability down to a few Hz for sub-audible tones and digitalsquelch codes. A two point modulation scheme is used with the audio also being fed tothe VCO to modulate the higher audio frequencies.The 12.8 MHz output of XO1 is amplified by Q22 to drive the reference input of thePLL synthesizer IC U6. This IC is a single chip synthesizer which includes a 1.1 GHzpre-scaler, programmable divider, reference divider and phase/frequency detector. Thefrequency data for U6 is supplied through serial data link by the microprocessor.The phase detector output signals of U6 are used to control two switched currentsources. The output of the positive and negative sources (Q3 and Q6) produces thetuning voltage which is smoothed by the loop filter components to bias the VCOvaractor diode D3.5.3 Power AmplifierThe 4 mW output from the main board connects to the power amplifier board through ashort miniature 5Ω coaxial cable.Q2 on the power amplifier board increases the signal to approximately 200 mW. Thebias current of Q2 is controlled by Q1 and the power leveling circuitry to adjust thedrive to the output module U2.U2 increases the power to 10-30 watts (depending upon options) before it is fed to thedirectional coupler, low pass filter and output connector. The directional couplerdetects the forward and reverse power components and provides proportional dcvoltages which are amplified by U1a and U1b. The forward and reverse voltages fromU1a and U1b are compared to the DC reference voltage from RV1. The difference isamplified by U1c, Q3 and Q4.
RF Technology T350/T500Page 115 CIRCUIT DESCRIPTION 5.3 Power AmplifierThe resulting control voltage supplies Q2 through R10, R12 and completes the powerleveling control loop.5.4 600Ω Line InputThe 600Ω balanced line input connects to line isolation transformer T1. T1 has two150Ω primary windings which are normally connected in series for 600Ω lines. Thedual primary windings can be used to provide DC loop PTT signaling or a 2/4 wirehybrid connection. All four leads are available at the rear panel system connector.The secondary of T1 can be terminated with an internal 600Ω load through JP5 or leftun-terminated in high impedance applications.5.5 Direct Coupled Audio InputA high impedance (10kΩ) direct AC coupled input is available at the system connector.The direct coupled input connects to U9a which is configured as a unity gain bridgeamplifier.The bridge configuration allows audio signal inversion by interchanging the positiveand negative inputs and minimizes ground loop problems. Both inputs should beconnected, with one lead going to the source output pin and the other connected to thesource audio ground.5.6 Local Microphone InputThe local microphone input is provided for use with a standard low impedance dynamicmicrophone. The microphone output is amplified by U9a before connecting to analogueswitch U10a. U10b inverts the local microphone PTT input to switch U10a ON whenthe microphone PTT button is pressed. U10a is OFF at all other times.The local microphone audio has priority over the other inputs. Activation of the localmicrophone PTT input switches OFF the audio from the line or direct inputs throughD16 and U10c.5.7 CTCSS and Tone FilterThe CTCSS encoder module H1, under control of the main microprocessor U13, canencode all 38 EIA tones and (on some models) additional commonly-used tones.The tone output of H1 connects to jumper JP8 which is used to select either H1 or anexternal tone source. The selected source is coupled to U9c which is a balanced inputunity gain amplifier. The buffered tone from U9c is fed to 300 Hz low pass filter U7c.RV3, the tone deviation trimmer, is used to adjust the level of the tone
Page 12 RF Technology T350/T5005.8 Audio Signal Processing 5 CIRCUIT DESCRIPTIONfrom U7c before it is combined with the voice audio signal in the summing amplifierU7a.Back to back diodes D4 and D5 limit the maximum tone signal amplitude to preventexcessive tone deviation when external tone sources are used.5.8 Audio Signal ProcessingJumper JP4 selects either the line or direct input source. The selected source is thenconnected to JP6. JP6 can be removed to provide 20 dB attenuation when the inputlevel is above 10 dBm to expand the useful range of the line level trimmer RV4. Thewiper of RV4 is coupled to the input of the input amplifier U9d. U9d provides avoltage gain of ten before connecting to the input of analogue switch U10c.The outputs of U10a and U10c are connected to the frequency response shapingnetworks C52, R133 (for 750µs pre-emphasis) and C61, R55 (for flat response). JP7selects the pre-emphasized or flat response.The audio signal is further amplified 100 times by U7d. U7d also provides thesymmetrical clipping required to limit the maximum deviation. The output level fromU7d is adjusted by RV1, the deviation adjustment, before being combined with the toneaudio signal in the summing amplifier U7a.The composite audio from U7a is fed through the 3Khz low pass filter U7b. Thefiltered audio is coupled to the TCXO voltage tuning input and the modulation balancetrimmer RV2.RV2 adjusts level of the audio used to modulate the VCO. This primarily effects thedeviation of audio frequencies above 500 Hz. RV2 is used to balance the high and lowfrequency deviation to obtain a flat frequency response relative to the desiredcharacteristic.5.9 PTT and DC Remote ControlTwo main PTT inputs are provided. The first, a direct logic level input, is connected topin 3 of the system connector. The transmitter can be keyed by applying a logic low orground on pin 3. Pin 3 connects to the PTT logic and microprocessor through D10.DC current loop control can be used for remote PTT operation. The current loop can beconfigured by JP9, JP10 and JP11 for use with either a remote free switch or a remoteswitched source.Opto-isolator ISO1 is used to isolate the loop current signal from the transmitter PTTlogic. The loop current passes through the input of ISO1 and the output of ISO1connects to the PTT logic.
RF Technology T350/T500Page 135CIRCUIT DESCRIPTION 5.10 Microprocessor ControllerA bridge consisting of diodes D6, D8, D9 and D14 ensures correct operation regardlessof the current polarity. Q17 limits the current and D7 limits the voltage input to ISO1.Any low voltage current source capable of providing 2 mA at 4 V or switching circuitwith less than 4.8kΩ loop resistance can be used to switch the DC loop.The test PTT button on the front panel and the local microphone PTT button will alsokey the transmitter. Both of these also mute the line audio input. The microphone linealso enables that audio input.5.10 Microprocessor ControllerThe microprocessor controller circuit uses a single-chip eight bit processor and severalsupport chips. The processor U13 includes non-volatile EE memory for channelfrequencies, tones, and other information. It also has an asynchronous serial port, asynchronous serial port and an eight bit analogue to digital converter.The program is stored in U5, a CMOS EPROM. U4 is an address latch for the low orderaddress bits. U2 is used to read the channel select lines onto the data bus. U11 is anaddress decoder for U5 and U2. U3 is a supervisory chip which keeps the processorreset unless the +5 Volt supply is within operating limits. U1 translates theasynchronous serial port data to standard RS232 levels.The analogue to digital converter is used to measure the forward and reverse power,tuning voltage and dc supply voltage.The processor keys the VCO through Q10, switches the 9.2 Volt transmit line throughQ14 and Q16, and the alarm LED D1 through Q1.5.11 Voltage RegulatorThe dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. Theseries pass transistor Q23 is driven by error amplifiers Q8 and Q18. Q9 is used to startup the regulator and once the circuit turns on, it plays no further part in the operation.The +5 Volt supply for the logic circuits is provided by an integrated circuit regulatorU14 which is run from the regulated 9.4 Volt supply.6Field Alignment ProcedureThe procedures given below may be used to align the transmitter in the field. Normally,alignment is only required when changing operating frequencies, or after componentreplacement.

If in doubt, allow1.5dB cable and connector losses, and assume that the maximum rated power is 15W. This means nomore than 10W at the end of a 1m length of test cable. This pessimistic procedure is safe on all modelsmanufactured at the time of writing.
RF Technology T350/T500Page 177 SPECIFICATIONS7SPECIFICATIONS7.1 Overall DescriptionThe transmitter is a frequency synthesized, narrow band FM unit, normally used todrive a 50 watt amplifier. It can also be used alone in lower power applications.Various models allow 2-25W of output power to be set across a number of UHFfrequency bands. All necessary control and 600Ω line interface circuitry is included.7.1.1 Channel CapacityAlthough most applications are single channel, it can be programmed for up to 100channels, numbered 0 - 99. This is to provide the capability of programming allchannels into all of the transmitters used at a given site. Where this facility is used inconjunction with channel-setting in the rack, exciter modules may be “hot-jockeyed” orused interchangeably. This can be convenient in maintenance situations.7.1.2 CTCSSFull EIA sub-tone capability is built into the modules. The CTCSS tone can beprogrammed for each channel. This means that each channel number can represent aunique RF and tone frequency combination.7.1.3 Channel ProgrammingThe channel information is stored in non-volatile memory and can be programmed viathe front panel test connector using a PC and RF Technology software.7.1.4 Channel SelectionChannel selection is by eight channel select lines. These are available through the rearpanel connector. Internal presetting is also possible. The default (open-circuit) state is toselect channel 00.A BCD active high code applied to the lines selects the required channel. This can besupplied by pre-wiring the rack connector so that each rack position is dedicated to afixed channel. Alternatively, thumb-wheel switch panels are available.

The exciter PCB typically has a few components whose valuesvary from model to model depending upon operating frequency and local regulatoryconstraints. The RF PA PCB varies from model to model but to a greater extent. Atleast two different PCB layouts, and numerous variations, exist. This manual presentsthe circuits and parts lists for two representative variants. When ordering spare parts besure to specify the model exactly, in case the part you require is different in value fromthat specified in this manual.Older models (predating this manual) may not be covered by this manual. However,advances are evolutionary, and the information in this manual will be sufficient in mostcases to permit understanding and servicing of all models, past and present.Versions of more detailed circuit schematics, printed on A3 paper, may be inserted orbound with this manual towards the end. It is sometimes easier to work with these fold-out diagrams because of their larger format. In case the inserts / fold-outs are missingor damaged, the reader is advised that information in the figures included with the textshould be identical.A.1 Block DiagramFigure 1 shows the block signal flow diagram.A.2 Circuit DiagramsFigure 2 shows the detailed circuit diagram with component numbers and values for themain (exciter) PCB. Figure 3 shows the detailed circuit diagram with componentnumbers and values for the higher-power PA variation. Figure 4 shows the detailedcircuit diagram with component numbers and values for the lower-power PA variation.
