MICROWAVE CORPORATION v03.0701 HMC253QS24 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 2.5 GHz Typical Applications Features The HMC253QS24 is ideal for DC - 2.5 GHz applications: Low Insertion Loss (2 GHz): 1.3dB Single Positive Supply: Vdd = +5V • CATV/DBS Integrated 3:8 TTL Decoder • CDMA 24 Lead QSOP Package • Cellular/PCS Functional Diagram General Description The HMC253QS24 is a low-cost non-reflective SP8T switch in a 24-lead QSOP package featuring wideband operation from DC to 2.5 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 3:8 decoder is integrated on the switch requiring only 3 control lines and a positive bias to select each path. The HMC253QS24 SP8T will replace multiple configurations of SP4T and SPDT MMIC switches.

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.
