5. Figure 1 The step frequency of the PLL circuit is 5 0KHz 6 25KHz 10 0KHz or 12 5KHz selectable Therefore the 38 4MHz reference oscillator signal is divided into 5 0KHz 6 25 KHz 10 0 KHz or 12 5 KHz reference frequencies via a fixed counter in the PLL at U202 Meantime the signal from the VCO goes through the buffer Q102 and amplifier Q103 and then it goes to the PLL at U202 where it is divided by a variable frequency divider In the phase detector PD of PLL the new signal derived from frequency division is compared with the reference frequencies After passing through a low pass filter the signal from the phase comparator goes to the varactors D100 D101 D102 and D103 of VCO so as to control its output frequency 2 VCO The VCO section is realized by the oscillator circuit of three point capacitance 11 610 In Tx mode the oscillator frequency of VCO is generated 0100 Rx mode it is generated 0101 U202 generates via the phase comparator a control voltage to control varactors D100 and D101 in Tx mode D102 and D103 in Rx mode making the oscillator frequency of VCO be consistent with the preset frequency of MCU within a wide frequency range Q652 performs switching between transmission and reception under the control of T R in Tx mode T R is set to low level and Q653 is turned on making Q100 operate
