VCTCXO is used for voltage supply for reference frequency of main set input.
It creates 16.8MHz frequency and input to PLL IC.
It controlled by voltage for exact frequency tuning.
12. PLL(Phase locked Loop)
PLL(PLL2) is frequency combiner of Dual mode. It output IF signal and Local signal if
demultiplied signal and Phase of phase comparator is same.
13. Regulator
Regulator is used for authorization for regular voltage of VCO and RX circuit through
Battery voltage.
14. Driver Amplifier
Drive amplifier (U6) is circuit for promote efficiency through supply amplified signal
to power amp.
15. Power Amplifier
Power amplifier (U4) is amplifier circuit for the amplification of output signal in Drive
amplifier (U6) in order to transmit the signal to base station through Antenna.
