HMC253QS24 / 253QS24E v04.0805 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 2.5 GHz Typical Applications The HMC253QS24 / HMC253QS24E is ideal for DC - 2.5 GHz applications: • CATV/DBS • CDMA • Cellular/PCS Features Low Insertion Loss (2 GHz): 1.3dB Single Positive Supply: Vdd = +5V Integrated 3:8 TTL Decoder 24 Lead QSOP Package 9 SWITCHES - SMT Functional Diagram General Description The HMC253QS24 & HMC253QS24E are low-cost non-reflective SP8T switches in 24-lead QSOP packages 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 & HMC253QS24E SP8T will replace multiple configurations of SP4T and SPDT MMIC switches.

HMC253QS24 / HMC253QS24E SP8T Switch 103704 Eval Board [1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350 The circuit board used in the final application should be generated with proper RF circuit design techniques. 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.
