Description

The ATR0601 is a single IF GPS front-end IC, designed to meet the requirements of

mobile and automotive applications.

Excellent RF performance combined with low noise figure enables high quality GPS

solutions and it's very low power consumption fits perfectly to portable devices. Fea-

turing a balanced XTO and a fully integrated balanced frequency synthesizer, only few

external components are required.

The ATR0601 offers a complete autonomous mode, utilizing the on chip AGC in

closed loop operation, to set the gain of the IF VGA.

Alternatively, in combination with the Antaris

mum gain of the IF VGA can be computed and set by software, using the digital SDI

interface.
