ACE9020isaVHFoscillator, up-converterandprescaler.

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 transmit up-converter. The prescaler is a

dual two-modulus divider and drives the main synthesiser

input of the ACE9030. The SSB up-converter suppresses the

unwanted transmit sideband.

The VHF oscillator is buffered to drive the auxiliary

synthesiser input of the ACE9030 and is locked to the offset

frequency. This frequency is modulated by varying the

resonant frequency of the external tank circuit. Both this

oscillator and the UHF VCO drive the up-converting mixer to

generate the transmit signal.

Various power saving modes for battery economy are

included. These allow the transmit sections to be shut down

during stand-by and the whole chip can be shut down during

sleep mode. The circuit techniques used have been chosen to

minimise external components and at the same time give very

high performance.
