Sony CXG1091TN Datasheet

SP4T GSM Dualband Antenna Switch 5V + Logic

Description

The SP4T + logic is a high power antenna switch

MMIC for use in dualband GSM handsets.

One Antenna can be routed to either of the 2 Tx or
2 Rx ports. It operates from 3 CMOS control lines (Tx
ON/OFF and GSM900/1800 and Standby).

The Sony's J-FET process is used for low insertion
loss.

Features

• 3 CMOS compatible control lines

• 34dBm power handling at 5.0V (GSM900)

• Low second harmonic < – 30dBm at 34dBm

• Small package size: 16-pin TSSOP (3.9 × 4.1mm)

Applications

Dualband handsets using combinations of GSM900/GSM1800/GSM1900 and DECT

Structure

GaAs J-FET MMIC
