HMC641LP4E v01.0910 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 20 GHz Typical Applications Features The HMC641LP4E is ideal for: Broadband Performance: DC - 20 GHz • Telecom Infrastructure High Isolation: 45 dB @ 10 GHz • Microwave Radio & VSAT Low Insertion Loss: 2.3 dB @ 10 GHz • Military & Space Hybrids Integrated 2:4 TTL Decoder • Test Instrumentation 24 Lead 4x4 mm SMT Package: 16 mm² • SATCOM & Sensors General Description Functional Diagram The HMC641LP4E is a broadband non-reflective GaAs pHEMT SP4T switch in a compact 4x4 mm plastic 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 HMC641LP4E is controlled with 0/ -5V logic, exhibits fast switching speed and consumes much less DC current than pin diode based solutions. The HMC641LP4E is also available in die form as the HMC641.

U1 HMC641LP4E Switch PCB [2] 126508 Evaluation PCB [1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350 or Arlon FR4 The circuit board used in the application should use RF circuit design techniques. 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.
