HMC646LP2E

HMC646LP2E is a SPDT switch in a leadless DFN surface mount plastic package for use in transmit/receive and LNA protection applications which require very low distortion and high power handling of up to 40 watts with less than 10% duty cycle. This robust switch can control signals from 100 - 2100MHz and is ideal for TD-SCDMA / 3G repeaters, PMR, automotive telematics, and satellite subscriber terminal applications. The design provides exceptional P0.1dB of +46 dBm and +74 dBm IIP3 on the Transmit (Tx) port. The failsafe topology provides a low loss path from Tx to RFC, when no DC power is available. Applications include LNA protection & T/R switching, TD-SCDMA / 3G infrastructure, satellite subscriber terminals, private mobile radio & public safety handsets, automotive telematics.
