HMC253QS24E

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 9 Functional Diagram Features Low Insertion Loss (2 GHz): 1.3dB Single Positive Supply: Vdd = +5V Integrated 3:8 TTL Decoder 24 Lead QSOP Package 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.
