| v04.0404 MICROWAVE CORPORATION HMC252QS24 Features Low Insertion Loss (2 GHz): 0.9 dB Single Positive Supply: Vdd = +5V Integrated 3:6 TTL Decoder 24 Lead QSOP Package GaAs MMIC SP6T NON-REFLECTIVE SWITCH, DC - 3.0 GHz Typical Applications The HMC252QS24 is ideal for: * Base Station * CATV / DBS * MMDS & WirelessLAN * Test Equipment Functional Diagram General Description The HMC252QS24 is a low-cost non-reflective SP6T switch in a 24-lead QSOP package featuring wideband operation from DC to 3.0 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 3:6 decoder is integrated on the switch requiring only 3 control lines and a positive bias to select each path. The HMC252QS24 SP6T replaces multiple configurations of SP4T and SPDT MMIC switches and logic drivers. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, For TTL Control and Vdd = +5V in a 50 Ohm System Parameter Frequency DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.0 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.0 GHz "On State" DC - 2.5 GHz DC - 3.0 GHz 0.3 - 3.0 GHz 0.5 - 2.5 GHz 0.3 - 3.0 GHz 0.3 - 3.0 GHz 0.3 - 3.0 GHz 35 120 ns ns 38 32 29 26 14 7 8 11 21 42 Min.

Signal lines at the RF ports should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown above. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request.
