HMC253QS24 253QS24E / v04.0805 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 2.5 GHz Typical Applications Features The HMC253QS24 / HMC253QS24E is ideal for Low Insertion Loss (2 GHz): 1.3dB DC - 2.5 GHz applications: Single Positive Supply: Vdd = +5V • CATV/DBS Integrated 3:8 TTL Decoder • CDMA 24 Lead QSOP Package • Cellular/PCS 9 Functional Diagram General Description The HMC253QS24 & HMC253QS24E are low-cost non-refl ective SP8T switches in 24-lead QSOP T packages featuring wideband operation from DC M to 2.5 GHz. The switch offers a single positive bias S 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 S E HMC253QS24 & HMC253QS24E SP8T will replace H multiple confi gurations of SP4T and SPDT MMIC C switches.
