General Description
The HMC-C071 is a general purpose broadband
high isolation non-reflective GaAs pHEMT SP4T
switch housed in a miniature hermetic module with
field replaceable SMA connectors. Covering DC to
20 GHz, the switch offers high isolation and low
insertion loss. The switch features >42 dB isolation
up to 12 GHz and >32 dB isolation up to 20 GHz. The
HMC-C071 also provides 2.8 dB insertion loss up to
12 GHz with very fast rise and fall times of 17ns. A
CMOS interface allows a single +5V bias voltage at
very low DC currents.
