HMC347G8

v02.0605 Typical Applications The HMC347G8 is ideal for: Telecom Infrastructure Microwave Radio & VSAT Military Radios, Radar & ECM Test Instrumentation HMC347G8 GaAs MMIC HERMETIC SMT SPDT SWITCH, DC - 8 GHz Features Isolation: 42 dB @ 2.5 GHz 30 dB @ 6 GHz Insertion Loss: 2 dB @ 6 GHz Non-Reflective Design 8 Lead Hermetic SMT Package 10 Functional Diagram General Description The HMC347G8 is a broadband high isolation nonreflective 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.
