Dual Path RF Switch with LNA

and 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 I_DD.

• +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.

. 50Ω single-ended input / output amplifier impedances

I_DD= 130mA

Independent Standby Mode for power savings

Supply voltage: +3.15V to +3.45V

5 × 5 mm, 32-LGA package

Competitive Advantage

-40°C to +105°C exposed pad operating temperature range

High integration

Low noise and high linearity

On-chip matching and bias

Extremely low current consumption
