Description

The CXG1077TN is a SPDT (Single Pole Dual Throw) antenna switch MMIC used in personal communication handsets such as JCDMA. This IC is designed using the Sony’s GaAs J-FET process.

Features

• Low control voltage Vctl (H) =2.8 V

• Low control current Ictl=30 µA (Typ.) @2.8 V

• Low insertion loss 0.35 dB (Typ.) @900 MHz

• High power handling P1dB: 33 dBm (Typ.) @900 MHz

• High intercept point Ip3=60 dBm (Typ.)

• Small package TSSOP-10pin

Application

SPDT switch for digital cellular telephones such as

JCDMA handsets.
