HMC344LC3 v03.0514 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8 GHz Typical Applications Features The HMC344LC3 is ideal for: Broadband Performance: DC - 8 GHz Broadband, Military, Radar & ECM Integrated 2:4 TTL Decoder Fiber Optics High Isolation: 40 dB 6 GHz Switched Filter Banks Low Insertion Loss: 2 dB 6 GHz Wireless below 8 GHz Non-Reflective Topology Test Instrumentation Functional Diagram General Description The HMC344LC3 is a broadband non-reflective GaAs MESFET SP4T switch in a ceramic 3x3 mm leadless surface mount package. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. The HMC344LC3 includes an integrated 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.
