CXG1131ER

24 pin VQFN (Plastic)

High Power 3

××××× 5 Antenna Switch MMIC with Integrated Control Logic

Description

The CXG1131ER is a high power antenna switch

MMIC for PDC full packet 1.5GHz handsets. This IC is

suited to connect Tx/Rx/duplexer to one of 4 antennas.

The CXG1131ER has on-chip logic circuit for operation

with 4 CMOS inputs. The Sony's GaAs J-FET process

is used for low insertion loss and low voltage operation.

Features

• Low insertion loss: 1.0dB @1.5GHz

• High linearity: Harmonic < – 65dBc

• CMOS compatible input control

• Small package: 24-pin VQFN (4.0mm

× 4.0mm)

Applications

3

× 5 antenna switch for digital cellular such as PDC handsets
