L-BAND SP3T SWITCH
DESCRIPTION
The
µ
PG2045TQ is an L-band SP3T GaAs FET switch which was developed for CDMA/PCS/GPS triple mode
digital cellular telephone application. The device can operate from 500 MHz to 2.0 GHz, having the low insertion loss
and high linality by 2.4 V low control voltage.
FEATURES
• Low insertion loss
• High power
