MOZART SERIES – Low Power FM Exciters/Transmitters - TECHNICAL MANUAL 102 /127 Circuit description of the Mozart transmitter. The Mozart line of transmitters share several circuits between models. The transmitter itself consists of a VCO/PLL board, control board and RF amplifier board. The VCO PLL board, contains all the frequency generation circuitry and is followed by the RF amplifier board which also contains the harmonic filtering circuitry. The power supply voltage for the RF amplifier stage of the board is 48Vdc. The RF amplifier board also contains RF protection and monitoring circuits that measure current draw, voltage output, SWR, and RF power output. The difference between models is the model of RF MOSFET used in this final stage. The VCO consists of a varactor tuned Colpitts oscillator with 2 buffer stages and an additional series voltage regulator for the VCO/ buffer. The PLL/ VCO board not only is responsible for frequency control but has the driver stage for the power amplifier. The PLL uses a voltage tuned TCXO at 10 MHz as its reference.
