HMC641LC4 v00.0609 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 20 GHz Typical Applications Features The HMC641LC4 is ideal for: Broadband Performance: DC - 20 GHz • Telecom Infrastructure High Isolation: 42 dB @ 12 GHz • Microwave Radio & VSAT Low Insertion Loss: 2.1 dB @ 12 GHz • Military & Space Hybrids Integrated 2:4 TTL Decoder • Test Instrumentation 24 Lead 4x4mm SMT Package: 16mm2 • SATCOM & Sensors General Description Functional Diagram 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.

Signal lines should have 50 Ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
