| HMC347C8 v01.0404 GaAs MMIC SMT HIGH ISOLATION SPDT SWITCH, DC - 8.0 GHz Features Isolation: 50 dB @ 2.5 GHz 36 dB @ 8.0 GHz Insertion Loss: 2.0 dB Typical Non-Reflective Design Surface Mount Ceramic Package Typical Applications The HMC347C8 is ideal for: * Telecom Infrastructure * Microwave Radio & VSAT * Military Radios, Radar & ECM 8 SWITCHES - SMT * Test Instrumentation Functional Diagram General Description The HMC347C8 is a broadband high isolation nonreflective GaAs MESFET SPDT switch in a non-hermetic surface mount ceramic package. Covering DC to 8.0 GHz, the switch features >50 dB isolation up to 2 GHz and >35 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 an excellent replacement for the HMC132C8 SPDT.
