Functional Diagram
General Description
The HMC446 is a low-cost SPDT switch in a 6-lead
SOT26 package for use in transmit-receive applica-
tions which require very low distortion at high signal
power levels, up to 10 watts. The device can con-
trol 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 con-
trol input (Vctl).
