HMC547LC3 v00.0811 Switches - SPDT - SMT GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 28.0 GHz Typical Applications Features The HMC547LC3 is ideal for: High Isolation: 45 dB @ 10 GHz 40 dB @ 20 GHz • Fiber Optics & Broadband Telecom Low Insertion Loss: 1.6 dB @ 10 GHz 1.9 dB @ 20 GHz • Microwave Radio & VSAT • Military Radios, Radar, & ECM Fast Switching: 6 ns • Test Instrumentation Non-Reflective Design 16 Lead Ceramic 3x3 mm SMT Package: 9mm2 Functional Diagram General Description The HMC547LC3 is a general purpose broadband high isolation non-reflective GaAs MESFET SPDT switch in a ceramic 3x3 mm leadless surface mount package. Covering DC to 28.0 GHz, the switch offers over 40 dB isolation and less than 2 dB insertion loss at midband. The wide bandwidth, fast switching, and compact size make this absorbtive SPDT ideal for miliitary EW/ECM and test equipment applications. The switch operates using complementary negative control voltage logic lines of -5/0V and requires no bias supply.
