27. CIRCUIT A PLL circuit provides stable oscillation of the transmit fre quency and receive 1st LO frequency The PLL output com pares the phase of the divided VCO frequency to the refer ence frequency The PLL output frequency is controlled by the divided ratio N data of a programable divider The PLL circuit contains the TX RX VCO circuit Q14 Q13 The oscillated signal is amplified at the buffer amplifiers 011 012 and then applied to the PLL IC IC4 pin 5 the low pass filter L32 C298 C299 The PLL IC contains a prescaler programable counter pro gramable divider and phase detector etc The entered sig nal is divided at the prescaler and programable counter sec tion by the N data ratio from the CPU The reference signal is generated at the reference oscillator X2 and is also applied to the PLL IC The PLL IC detects the out of step phase using the reference frequency and outputs it from pin 9 The output signal is passed thorough the loop filter and is then applied to the VCO circuit as the lock voltage If the oscillated signal drifts its phase changes from that of the reference frequency causing a lock voltage change to compensate for the drift in the oscillated frequency 4 3 2 VCO CIRCUIT The VCO circuit contains a separate RX VCO Q13 D16 and TX VCO Q14 D17 D18 The oscillated signal is ampli fied at the buffer amplifiers Q11 Q10 and is then applied to the T R switch circuit D14 D15 Then the
