| HMC347LP3 / 347LP3E v06.0805 GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 14.0 GHz Features High Isolation: >50 dB up to 3 GHz >45 dB up to 10 GHz Low Insertion Loss: 1.6 dB @ 10 GHz Non-Reflective Design 3x3 mm QFN SMT Package Typical Applications The HMC347LP3 / HMC347LP3E is ideal for: * Basestation Infrastructure * Fiber Optics & Broadband Telecom * Microwave Radio & VSAT 8 SWITCHES - SMT * Military Radios, Radar, & ECM * Test Instrumentation Functional Diagram General Description 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.
