HMC347LP3 v03.0604 MICROWAVE CORPORATION GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 14.0 GHz Typical Applications Features The HMC347LP3 is ideal for: High Isolation: >50 dB up to 3 GHz • Basestation Infrastructure >45 dB up to 10 GHz • Fiber Optics & Broadband Telecom Low Insertion Loss: 1.6 dB @ 10 GHz • Microwave Radio & VSAT Non-Reflective Design • Military Radios, Radar, & ECM 3 x 3 x 1 mm QFN SMT Package • Test Instrumentation General Description Functional Diagram The HMC347LP3 is a broadband high isolation non-reflective GaAs MESFET SPDT switch in a low cost leadless QFN surface mount plastic package. Covering DC to 14 GHz, the switch offers high isolation and low insertion loss. The switch features >50 dB isolation up to 3 GHz and >40 dB isolation up to 13 GHz. The switch operates using complementary negative control voltage logic lines of -5/0V and requires no bias supply. This SPDT is an excellent alternative to the HMC132C8 SPDT.
