The F0473B is an integrated dual-path RF front-end consisting of an RF switch and two gain stages with 6dB gain control used in the analog front-end receiver of an Active Antenna System (AAS). Supporting frequencies from 3.3GHz to 4.2GHz, the F0473B provides 35dB gain with +15dBm OP1dB, and 1.3dB noise figure (NF). Gain is reduced 6dB in a single step with a maximum settling time of 35ns.

The device uses a single 3.3V supply and 130mA of IDD. Offered in a 5 × 5 mm, 32-pin QFN package with 50Ω input and output amplifier impedances, the F0473B integrates into the signal path with the greatest of ease.
