DVGA 3300MHz to 4000MHz
F0453B
Datasheet
Description
Features
The F0453B 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 F0453B supports frequencies from 3300MHz to 4000MHz.

Gain at 3500MHz
34.5dB typical in High Gain Mode
28.5dB typical in Low Gain Mode
1.35dB NF at 3500MHz
+23dBm OIP3 at 3500MHz
OP1dB at 3500MHz

.
The F0453B provides 34.5dB gain with +23dBm OIP3, +15dBm
output P1dB, and 1.35dB noise figure at 3500MHz. Gain is
reduced 6dB in a single step with a maximum settling time of
31ns. The device uses a single 3.3V supply and 130mA of IDD.
+15dBm in High Gain Mode
+14dBm in Low Gain Mode
The F0453B is offered in a 5 5 0.8 mm, 32-LGA package with
50Ω input and output amplifier impedances for ease of integration
into the signal path.
