1. 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. Featuring a balanced XTO and a fully integrated bal-

anced 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

baseband processor ATR0621 the optimum gain of the IF VGA can be computed and

set by software, using the digital SDI interface.
