General Description
The HMC347G8 is a broadband high isolation
non-re鏗俥ctive GaAs MESFET SPDT switch in a 8
lead glass/metal (hermetic) surface mount pack-
age. Covering DC to 8.0 GHz, the switch features
>42 dB isolation up to 2 GHz and >25 dB isolation
up to 8.0 GHz. The switch operates using com-
plementary negative control voltage logic lines of
-5/0V and requires no bias supply. This SPDT is a
good replacement for the HMC132G7 SPDT.
