The F0472 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). The F0472 supports frequencies from 2.3GHz to 2.7GHz. 

The F0472 provides 34dB gain with +15dBm OP1dB, and 1.2dB 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. 

The F0472 is offered in a 5 × 5 × 0.8 mm, 32-pin package with 50Ω input and output amplifier impedances for ease of integration into the signal path.
