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