1. Description
The ATR0610 is a GPS low-noise amplifier IC designed for GPS applications. The
part uses Atmel’s SiGe1 SiGe technology and is optimized for high linearity, low-noise
figure, low BOM and low power consumption. The part features an integrated 50Ω out-
put match and is prematched at the input. Due to internal supply blocking, the BOM is
minimized. Together with the small footprint of 1.6 mm × 2.0 mm, the LNA allows for a
very compact GPS receiver design.
