Dual Path RF Switch with LNA
and DVGA 2.3GHz to 2.7GHz
F0452C
Datasheet
Description
The F0452C 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
F0452C supports frequencies from 2.3GHz to 2.7GHz.
The F0452C provides 34dB gain with +23dBm OIP3, +15dBm
output P1dB, and 1.6dB noise figure (NF) at 2.6GHz. Gain is
reduced 6dB in a single step with a maximum gain settling time of
31ns. The device uses a single 3.3V supply and 130mA of IDD.
The F0452C is offered in a 6 × 6 × 0.75 mm, 32-pin LGA package
with 50Ω input and output amplifier impedances for ease of
integration into the signal path.
Competitive Advantage
High integration
Low noise and high linearity
On-chip matching and bias
Extremely low current consumption
