HMC347G8
GaAs MMIC HERMETIC SMT SPDT
SWITCH, DC - 8.0 GHz
Features
Isolation: 42 dB @ 2.5 GHz
30 dB @ 6.0 GHz
Insertion Loss: 2.0 dB @ 6.0 GHz
Non-Refl ective Design
8 Lead Hermetic SMT Package
General Description
The HMC347G8 is a broadband high isolation
non-refl ective GaAs MESFET SPDT switch in a 8
lead glass/metal (hermetic) surface mount package. 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 complementary negative control voltage logic lines of
-5/0V and requires no bias supply. This SPDT is a
good replacement for the HMC132G7 SPDT.
