NX-800 18 3. Receiver System 3-1. RF circuit The front-end circuit consists of former BPF (D212, D213), RF amplifier Q210, and latter BPF (D207, D208, D209 and D210). The BPF covers frequency ranges 450 to 520MHz. The latter BPF (D207, D208, D209 and D210) attenuates the unwanted signals, and sends only the necessary signal to the first mixer.
NX-800 19 3-3. IF circuit The first IF signal is passed through a four-pole monolithic crystal filter (XF202) to reject adjacent channel signal. The filtered first IF signal is amplified by the first IF amplifier (Q204, Q205) and then applied to the lF system IC (IC202).
NX-800 20 4-3. Drive and Final amplifier The transmit signal obtained from the TX VCO buffer am- plifier Q9, is amplified to approximately +17dBm by the driver amplifiers Q10, Q101 and Q102.
NX-800 21 CIRCUIT DESCRIPTION 5. PLL Frequency Synthesizer 5-1. VCTCXO (X1) VCTCXO (X1) generates a reference frequency of 19.2MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 9 of the PLL IC (IC3) and connected to IF circuit as a 2nd local signal through Tripler.
NX-800 22 6. Control Circuit The control circuit consists of CPU (IC510) and its periph- eral circuits. IC510 mainly performs the following; 1) Switching between transmission and reception by PTT signal input. 2) Reading system, zone, frequency, and program data from the memory circuit.
