HMC344LH5 v00.0805 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 12 GHz Typical Applications This switch is suitable for DC - 12.0 GHz 50-Ohm Systems • Telecom Infrastructure • Military Radio, Radar & ECM Features Broadband Performance: DC - 12 GHz High Isolation: 42 dB@ 6 GHz Low Insertion Loss: 1.8 dB@ 6 GHz Integrated 2:4 TTL Decoder Hermetic SMT Package, 25 mm2 Screening to MIL-PRF-38535 (Class B or S) Available 8 SWITCHES - SMT • Space Systems • Test Instrumentation Functional Diagram General Description The HMC344LH5 is a broadband non-reflective GaAs MESFET SP4T switch in a hermetic SMT leadless package. Covering DC to 12 GHz, this switch offers high isolation and low insertion loss. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fixed bias of -5V. Simple external level shifting circuitry allows this switch to be controlled with most TTL/CMOS positive logic families. The HMC344LH5 allows the use of surface mount manufacturing techniques and is suitable for high reliability military, industrial and space applications.
