TK - 2 1 02 G 6 CIRCUIT DESCRIPTION 1. Frequency Confi guration The receiver utilizes double conversion. The first IF is 38.85MHz and the second IF is 450kHz. The fi rst local oscil- lator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the neces- sary frequencies.
TK - 2 1 02 G 7 CIRCUIT DESCRIPTION XF200:L71-0522-05 Item Rating Nominal center frequency 38.850MHz Pass band width ±5.0kHz or more at 3dB 40dB stop band width ±20.
TK - 2 1 02 G 8 CIRCUIT DESCRIPTION Fig. 4 PLL circuit Fig. 6 T ransmit audio and QT/DQT encoder 3) Unlock Detector If a pulse signal appears at the LD pin of IC1, an unlock condition occurs, and the DC voltage obtained from D7, R1, and C1 causes the voltage applied to the UL pin of the mi- croprocessor to go low .
TK - 2 1 02 G 9 CIRCUIT DESCRIPTION 3) VCO and RF Amplifi er The transmit signal obtained from the VCO buffer am- plifi er Q100, is amplifi ed by Q101. This amplifi ed signal is passed to the power amplifi er , Q102 and Q105, which con- sists of a 2-stage FET amplifi er and is capable of producing up to 5W of RF power .
