Dual Path RF Switch with LNA
and DVGA 3300MHz to 4000MHz
F0453C
Datasheet
Description
Features
The F0453C 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 F0453C supports frequencies from 3300MHz to 4000MHz.
.
Gain at 3500MHz
• 35dB typical in High Gain Mode
• 29dB typical in Low Gain Mode
1.35dB NF at 3500MHz
+23dBm OIP3 at 3500MHz
OP1dB at 3500MHz
.
.
.
The F0453C provides 35dB 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 gain 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 F0453C is offered in a 6 × 6 × 0.75 mm, 32-LGA package
with 50Ω input and output amplifier impedances for ease of
integration into the signal path.
