The HMC546LP2E is a failsafe SPDT switch in a leadless DFN surface-mount plastic package for use in transmit/receive and LNA protection applications that require very low distortion and high power handling of up to 10 watts.The HMC546LP2E requires external matching and is suitable for narrow-band applications within 200 MHz to 2700 MHz.This narrow-band switch is well suited for WiMAX and WiBro repeaters, private mobile radio (PMR), and automotive telematic applications. The design provides exceptional P0.1dB of 40 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.ApplicationsLNA protection, WiMAX, and WiBroCellular, PCS, 3G, and TD-SCDMA infrastructurePrivate mobile radio and public safety handsetsAutomotive telematics
