NJG1658K34

DP7T ANTENNA SWITCH GaAs MMIC

GENERAL DESCRIPTION

NJG1658K34 is a GaAs DP7T antenna switch IC designed for

WCDMA/GSM multimode handsets. This switch can be operated

by six bits control signal from 1.3V of logic high voltage. This

switch features low insertion loss and low distortion. Also, the ESD

protection circuit is integrated into the IC to achieve high ESD

tolerance.

The small and thin QFN24-34 package is adopted.
