| HMC641LC4 v00.0609 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 20 GHz Typical Applications The HMC641LC4 is ideal for: * Telecom Infrastructure * Microwave Radio & VSAT * Military & Space Hybrids * Test Instrumentation * SATCOM & Sensors 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 Functional Diagram 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. 11 SWITCHES - SPDT - SMT Electrical Specifi cations, TA = +25 C, With 0/-5V Control, Vss = -5V, 50 Ohm System Parameter Insertion Loss Isolation (RFC to RF1 - RF4) Return Loss Return Loss Input Power for 1 dB Compression Input Third Order Intercept (Two-Tone Input Power= +14 dBm Each Tone) Switching Characteristics tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) "On State" "Off State" Frequency DC - 12 GHz DC - 20 GHz DC - 12 GHz DC - 20 GHz DC - 12 GHz DC - 20 GHz DC - 20 GHz 0.05 - 0.25 GHz 0.25- 20 GHz 0.05 - 0.25 GHz 0.25 - 20 GHz DC - 20 GHz 10 20 30 30 Min.

HMC641LC4 Switch 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.
