It is packaged in a 2 x 2 x 0.5mm, 12pin QFN. Features include: a single supply voltage of 2.7 to 4.8V; and integrated 5GHz LNA with Bypass and SPDT. Applications include: IEEE802.11a WiFi applications; IEEE802.11p wave automotive mesh; consumer electronics; mobile devices; gaming; and general purpose switch and LNA solution for 4.9 to 5.85GHz frequency range.
