Receiver and Transmitter Interface

ACE9020 is a VHF oscillator, up-converter and prescaler. It is used in an offset modulated transmit architecture where a UHF synthesiser makes the channel selection and a second synthesiser generates a fixed transmit offset. A VCO signal drives a buffer in ACE9020 to feed an on chip prescaler and
