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.
Q FEATURES
O Low insertion loss
