Preliminary

1. Description

The ATR2730 is a monolithically integrated L-band down-converter circuit fabricated

with Atmel^®’s advanced UHF5S technology. This IC covers all functions of an L-band

down-converter in a DAB receiver. The device includes a gain-controlled amplifier, a

gain-controlled mixer, an output buffer, a gain control block, a power-save function for

the analog part, an L-band oscillator, and a complete frequency synthesizer unit. The

frequency synthesizer block consists of a reference oscillator/buffer, a reference

divider, an RF divider, a tri-state phase detector, a loop filter amplifier, a lock detector,

a programmable charge pump, a test interface, and a control interface.
