General Description

The HMC641ALC4 is a broadband non-reflective GaAs pHEMT SP4T switch in a compact 4×4 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 HMC641ALC4 is controlled with 0/ -5V logic, exhibits fast switching speed and consumes much less DC current than pin diode based solutions.
