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 lowpower 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 ...
