General Description
The HMC347C8 is a broadband high isolation
non-re鏗俥ctive GaAs MESFET SPDT switch in
a
non-hermetic
surface mount ceramic package.
Covering DC to 8.0 GHz, the switch features >50
dB isolation up to 2 GHz and >35 dB isolation up
to 8.0 GHz. The switch operates using comple-
mentary negative control voltage logic lines of -5/
0V and requires no bias supply. This SPDT is an
excellent replacement for the HMC132C8 SPDT.
