High Input P0.1 dB: +40 dBm Tx
Positive Control: 0/+5V to 0/+8V
Ultra Small Package: SOT26
General Description
The HMC446 & HMC446E are low-cost SPDT swit-
ches in 6-lead SOT26 packages for use in transmit-
receive 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 auto-
motive 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).
