HMC344LC3

SWITCHES - MULTI-THROW - SMT v03.0514 Typical Applications The HMC344LC3 is ideal for: Broadband, Military, Radar & ECM Fiber Optics Switched Filter Banks Wireless below 8 GHz Test Instrumentation Functional Diagram HMC344LC3 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8 GHz Features Broadband Performance: DC - 8 GHz Integrated 2:4 TTL Decoder High Isolation: 40 dB@ 6 GHz Low Insertion Loss: 2 dB@ 6 GHz Non-Reflective Topology 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.
