Product Description
TQM640002 RF front end module (FEM) is an active device for GPS applications
(center frequency 1575.42 MHz). It is designed for simultaneous GPS + voice in
multi-function handsets. The FEM is comprised of a low-power flip-chip LNA die,
a pair of high-performance SAW filters, and integrated passive matching circuitry.
The module will operate at 1.8v or 2.8v bias and its current consumption –
typically 5.0 mA – is not changed by DC supply, making it suitable for use in low-
power applications & during low-battery situations. The FEM performance exhibits
high in-band gain and excellent rejection in all the key cellular & WLAN/Bluetooth
bands. The device also exhibits both a high intercept point & a low noise figure,
which optimally addresses today’s most stringent GPS front end receiver
requirements.
