1. Description

The ATR2732N1 is a front-end monolithic integrated circuit, manufactured using

Atmel^®’s silicon-germanium BiCMOS process (SiGMOS).

The ATR2732N1 carries out all functions of RF and IF processing, as well as the

clock-signal generation for these functions. Therefore, there is an integrated fractional

PLL, which, equivalent to most of the other functions, can be controlled via an external

digital bus. The RF functions include LNA, down-conversion mixing, amplifying, detec-

tion, and gain control. An external SAW filter is required in the signal path after the RF

functions. Additional amplifiers with detection and control functions are integrated IF

functions.

The device offers several tuning support functions, and was created to simplify the

design and manufacturing process. To this end, the number of external components

are minimal.

The part fits perfectly to Atmel’s DAB baseband processor ATR2740.
