Low noise amplifiers

The superior RF performance of the fully-integrated SMA661AS from STMicroelectronics makes it the leading solution for GPS LNA implementation in cell phones and personal navigation devices. The SMA661AS embeds the matching network and the power-down function to avoid the requirement for an external switch. Housed in an ultra miniature SOT666 plastic package, the SMA661AS requires just one external capacitor, minimizing PCB footprint. It is powered by ST’s high-performance RF SiGe 70-GHz technology.
