Description

The ATR0610 is a 2.7-V GPS low-noise amplifier IC designed for use in GPS applica-

tions. It uses a SiGe HBT die. The IC is 50-W matched on the output allowing the

device to be used with minimal external circuitry. Its RF performance meets the

requirements for products designed to the GPS standard.

The ATR0610 gives excellent RF performance with low current consumption resulting

in longer battery life times. The package has a small 1.6 mm ´ 2.0 mm footprint to

allow use in compact GPS receiver design.
