General Description
The HMC446 & HMC446E are low-cost SPDT switches in 6-lead SOT26 packages for use in transmitreceive applications which require very low distortion at high signal power levels, up to 10 watts. The device can control signals from 824 - 894 MHz* and is especially suited for cellular booster and automotive telematic applications. The design provides exceptional P0.1 dB of +40 dBm and +65 dBm IIP3 on the Transmit (Tx) port. The Tx port is a reflective open when “Off” while the Rx port is a reflective short when “Off”. On-chip circuitry allows single positive supply operation at very low DC current with a single control input (Vctl).
