The HMC641 is a broadband nonreflective GaAs pHEMT SP4T switch chip in a compact 4 mm x 4 mm ceramic or plastic package. Covering DC to 20 GHz, this switch offers high isolation, low insertion loss, on-chip termination of isolated ports, and extends the frequency coverage of the SP4T switch product line. This switch also includes an on-board binary decoder circuit that reduces the number of required logic control lines to two. The switch operates using a negative control voltage of 0/−5 V, requires a fixed Vss bias of −5 V, and exhibits fast switching speed and consumes much less dc current than pin diode-based solutions. All data are tested with the chip in a 50 Ω test fixture connected via one 3.0 mil x 0.5 mil gold ribbon of minimal length on each RF port. The HMC641 is available in die form.
