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