The requires external matching and is suitable for narrow-band applications within 2 MHz to 27 MHz. W, Failsafe, GaAs, SPDT Switch.2 GHz to 2.7 GHz FUNCTIONAL BLOCK DIAGRAM Tx V CTL 2 6 RFC ACG 3 4 Rx Figure. 5 V DD PACKAGE BASE This narrow-band switch is well suited for WiMAX and WiBro repeaters, private mobile radio (PMR), and automotive telematic applications. The design provides exceptional P.dB of 4 dbm and IIP3 of 65 dbm on the transmit (Tx) port. The failsafe topology allows the switch to provide a low loss path from RFC to Tx, when no dc power is available Rev.
