HMC347LP3 / 347LP3E v06.0805 GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 14 GHz Typical Applications Features The HMC347LP3 / HMC347LP3E is ideal for: High Isolation: >50 dB up to 3 GHz >45 dB up to 10 GHz • Basestation Infrastructure • Fiber Optics & Broadband Telecom Low Insertion Loss: 1.6 dB @ 10 GHz • Microwave Radio & VSAT Non-Reflective Design • Military Radios, Radar, & ECM 3x3 mm QFN SMT Package • Test Instrumentation General Description Functional Diagram The HMC347LP3 & HMC347LP3E are broadband high isolation non-reflective GaAs MESFET SPDT switches in low cost leadless QFN surface mount plastic packages. 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.
