DESCRIPTION
FMM5309ZU is a high power SP3T GaAs PHEMT switch designed for transmit / receive switching
applications in the 0.5 GHz to 2.5 GHz range. FMM5309ZU is ideally suited for applications where
high linearity, low control voltage, low insertion loss, high isolation, small size and low cost are
required. Typical applications are for UMTS, GSM and CDMA handset systems. The device is in low-
cost miniature QFN 12-lead 3x3mm package.
