NJG1658K34 DP7T ANTENNA SWITCH GaAs MMIC Q 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.
