| v01.0404 MICROWAVE CORPORATION HMC347C8 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 * Test Instrumentation Functional Diagram General Description The HMC347C8 is a broadband high isolation non-reflective 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. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, With 0/-5V Control, 50 Ohm System Parameter Frequency DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz 0.5 - 8.0 GHz 0.5 - 8.0 GHz 19 38 49 35 32 10 7 6 Min.
