HMC253QS24 / 253QS24E v04.0805 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 2.5 GHz Typical Applications Features The HMC253QS24 / HMC253QS24E is ideal for DC - 2.5 GHz applications: Low Insertion Loss (2 GHz): 1.3dB • CATV/DBS Integrated 3:8 TTL Decoder • CDMA 24 Lead QSOP Package Single Positive Supply: Vdd = +5V • Cellular/PCS 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.

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.
