Sony CXG1131ER Datasheet

CXG1131ER
High Power 3
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
