262.1 OPERATING ENVIRONMENTYou can install the apparatus in a standard component rack or on a suitable surface such as a bench or desk.In any case, the area should be as clean and well-ventilated as possible. Do not locate the transmitter directlyabove a hot piece of equipment. The upper lid can be dismounted to allow an easy internal access. Theequipment is designed with a modular design, that is each circuit is realized inside different modules or boards.All interconnections between modules are made by means of connectable cables which allow an easy andquick maintenance of demaged modules.2.2 FIRST INSTALLATION1. Connect Antenna cable2. Connect AC POWER cord3. Select step and frequency with display interface4. Move power slowly up till nominal power and check the Reflected Power to be low.

303.1 USER INTERFACE AND SOFTWARE SETTINGSWhen the equipment is switched on, the display shows the presentation screen, containing the name of thedevice and the release number of the firmware.The mono/stereo choice is made automatically by MIZAR, detecting the presence of the Stereo CoderBoard (OPT023).At this stage the device restores the last configuration saved of power, frequency and all other parameters.The other menu can be accessed by pressing the UP and DOWN keys.All menus show the name of one or two parameter, which can be the reading of a status (e.g. lock/unlock) ora setting (e.g. Emphasis circuit ON/OFF). In the latter case, the setting may be changed by pressing the RETin the relevant menu. When the RET key is pressed while in a setting menu, the parameter name label startsblinking to show that the setting is being edited and not read.While the label blinks, the user can change the value shown by pressing the UP and DOWN keys. To exit theedit mode of a setting, and confirm any change made, press the RET key. To leave the edit mode withoutconfirming any change, press ESC.Pressing the ESC key while navigating into menu structure, the main menu with the presentation screen isreached.Some parameter can be modified only in a protected mode, this possibility willbe highlighted in the menu list. To enter in the protected mode switch on theMIZAR with both UP and DOWN key pressed. The confirmation of theprotected mode enter will be the display message below and the blinking redalarm led. This will remember that in protected mode all the alarms and protections will be disabled.The existing menu, in the order they can be accessed by pressing the UP key, are briefly described below.This shows the actual level of Forward and Reflected Power. The ForwardPower level can be adjusted.This shows the actual alarm threshold of Forward and Reflected Power.

It is possible to choose theModel of MIZAR FM Transmitter between 30W and 300W, between EKA,China and OIRT frequency bands. Remote DISABLED TLM Command ON3.2 AGC IMPLEMENTATIONThe AGC goal is to maintain stable the output power. Output power in fact can change due to the increase ofamplifier temperature. Note that when you change the operating frequency the output power change due tothe different gain at different frequency, but this change is not stabilized by this AGC algorithm.The AGC algorithm is based on the acquisition of the optimal output power level, stored when you changeMIZAR output power. To keep the power stable the AGC change the power gain of MIZAR. When the goalpower is achieved the AGC stops until the power moves up or down.The AGC work is stopped immediately (output power remains blocked to that reached in the moment of theAGC stop) when one of this condition occurs:• one of MIZAR alarms is triggered;• input power level is to low;• AGC has change the MIRA output power too much.
333.3 ALARMS AND AUTOMATIC BEHAVIOURSThe apparatus signals a working anomaly when any of the following conditions is met: PLL Unlock Forward Power exceed the threshold Reflected Power exceed the threshold Temperature of the Heat Sink exceed the maximum allowedIn case of failure of any of these parameters, the apparatus automatically mute the output power and changethe menu to the Log menu with the last alarm highlighted.

39MOTHER BOARD SCH0377AR2DESCRIPTIONThe board contains the stages needed to condition the audio MONO or RIGHT signals and modulate infrequency a synthesised oscillator. It provides an output radio frequency signal in the II-VHF band, to drivethe final amplification stage. The various sections are analysed below:1. Balanced/Unbalanced Converter: the conversion from balanced to unbalanced and the input interface of the audio signal are realised la electronically by the IC1-A operational circuit. This assures an high ge- gree of immunity from disturbances and a perfect symmetry in unbalancing.2. Pre-emphasis: after the level adjustment, there is the active pre-emphasis stage (IC1-B), with amplification to high frequencies. The time constant is chosen between 25 and 50 microseconds by means of two jum- pers (JP3-4). When they are both enables they give 75us (for the FCC standard). The insertion of the pre- emphasis is managed from the frontal panel by activating the electronic switch IC4.3. Low-pass Filter: the use of two filtering stages with elliptical filters LP1 and LP2 assures the adequate suppres- sion of input signals at frequencies 19k and 38kHz.4. Additioner: depending on the operating mode selected by the frontal panel (Stereo or Mono) the MONO signal, after the low-pass filter, is sent to the internal stereo coder (as RIGHT signal) or added to the auxi- liary inputs (SCA1-2 and MPX) in the stage composed by IC3-A.5. Peak Detector: at the output of the additioner, part of the signal is sampled for the indication of the devia- tion on the front panel. IC5-A serves as buffer for the duplicator and peak detector. Aside from the peak detector for the indication of the modulation level, the board also includes a second detector (IC5-B and D4) used to measure the level of the RIGHT signal.6. Limitation circuit: TR3 and TR4 realise the deviation limitation circuit by cutting the audio signal which exceeds the set voltage threshold on the relevant basis, by means of the resistor network R51-54.7. Oscillator: a frequency synthesis oscillator with PLL generates the radiofrequency carrier which is modulated in frequency in the same circuit. The reference frequency is generated by a 5.0MHz TCXO with good temperature stability.8. RF Driver: after the oscillator there is a PIN diode stage (D3) to check the amplitude of the signal and mo- dify the output power. The dynamic is greater than 40dB. The monolith amplifier (IC6) serves as buffer in order to make the load effects on the oscillator circuit irrelevant. Finally, the stage with TR7 amplifies the signal to the adequate levels for driving the power module. A circuit monitoring the power supply of TR7, composed by TR6 and TR8, activates to switch the transistor off in case of alarms (such as PLL unlock or any anomaly detected by the control board).
409. Telemetering: the most important analogue signals – forward and reflectesd power, switch on/off, alarms and temperature – are buffered and made available on the J5 socket for connecting remote control systems.SCH0377AR2 Component layout

5530W FM AMPLIFIER MODULE MFF0025BR0DESCRIPTIONThe MFF0025B amplifier module is designed to amplify the FM modulated carriers in the 87-108MHz band,and can provide an output of 30W CW. In order to obtain the desired gain, the amplifier is made up by twogain stages: the pilot stage uses a BLF242 MOSFET, while the final stage uses a BLF245 MOSFET.An input adaptation circuit allows the adaptation of the module to the various driving levels. The output powerregulation is made by controlling the power level of the input signal of the module. The final stage of themodule also has a control terminal allowing to disable the MOSFET immediately, if needed. The output of themodule is completed by a 9th order (4 cell) low-pass filter to attenuate the level of the harmonics of the signal,and by two high-directivity directional couplers needed to sample part of the Forward and Reflected Powerin order to measure their levels. The final is provided with the needed circuits (SCH0371B Interface Board)to read the output Forward and Reflected Power, the heatsink temperature and the voltage supplied.TECHNICAL CHARACTERISTICSFrequency Range 87 - 108MHzOutput Power 30WInput Return Loss >25dBPower Supply +27VRF Input Impedance 50ΩRF Output Impedance 50ΩBias Current BLF242 with Vdd = +27V: 220mABias Current BLF245 with Vdd = +27V: 220mAGain 20dBEfficiency 54%MFF0025BR0 COMPONENT LISTPart Name/Number Description Qty.SCH0382BR0 30W FM AMPLIFIER BOARD 101400 BYPASSING CAPACITOR 101408 BYPASSING CAPACITOR 3DET1304 DET1304R0 30W DISSIPATOR 1DET1276 DET1276R0 AMPLIFIER REAR BAR 1DET1277 DET1277R1 AMPLIFIER INPUT BAR 1DET1239 DET1239R1 AMPLIFIER MODULE COVER 1SCH0371BR0 INTERFACE BOARD 107907 TO220 INSULATOR 207910 TO220 INSULATOR 202515 SMB SCREW cod.
