ACE9020 Receiver and Transmitter Interface Supersedes February 1997 edition, DS4287 - 4.1 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 onchip prescaler and transmit up-converter.
The prescaler is a dual two-modulus divider and drives the main synthesiser input of the
