GPS receiver IC extends battery life

The PointCharger SE4100 SiGe GPS receiver
consumes one-third the power of competing bipolar
solutions-enabling longer battery-powered
operation. The part integrates an IF filter, a
VCO, tank circuitry, and an LNA onto a single
chip with a typical current draw of 10 mA from a
2.7-V supply.

.
Housed in a 24-pin LPCC package, the device
supports additional power-saving modes offered by
its companion baseband chips. ($3.50
ea/10,000-samples available now.)
