HMC641LC4

SWITCHES - SP4T - SMT v01.0514 Typical Applications The HMC641LC4 is ideal for: Telecom Infrastructure Microwave Radio & VSAT Military & Space Hybrids Test Instrumentation SATCOM & Sensors Functional Diagram HMC641LC4 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 20 GHz Features Broadband Performance: DC - 20 GHz High Isolation: 42 dB @ 12 GHz Low Insertion Loss: 2.1 dB @ 12 GHz Integrated 2:4 TTL Decoder 24 Lead 4x4mm SMT Package: 16mm² General Description The HMC641LC4 is a broadband non-reflective GaAs pHEMT SP4T switch in a compact 4x4 mm ceramic package. Covering DC to 20 GHz, this switch offers high isolation, low insertion loss and on-chip termination of isolated ports. This switch also includes an on board binary decoder circuit which reduces the number of required logic control lines from four to two. The HMC641LC4 is controlled with 0/ -5V logic, exhibits fast switching speed and consumes much less DC current than pin diode based solutions. The HMC641LC4 is also available in die form as the HMC641. Electrical Specifications, TA = +25° C, With 0/-5V Control, Vss = -5V, 50 Ohm System Parameter Frequency Min. Typ. Max.
