HMC252QS24 / 252QS24E v05.0505 GaAs MMIC SP6T NON-REFLECTIVE SWITCH, DC - 3 GHz Typical Applications Features The HMC252QS24 / HMC252QS24E is ideal for: Low Insertion Loss (2 GHz): 0.9 dB • Base Station Single Positive Supply: Vdd = +5V • CATV / DBS Integrated 3:6 TTL Decoder • MMDS & WirelessLAN 24 Lead QSOP Package • Test Equipment Functional Diagram General Description The HMC252QS24 & HMC252QS24E are low-cost non-reflective SP6T switches in 24-lead QSOP packages featuring wideband operation from DC to 3.0 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 3:6 decoder is integrated on the switch requiring only 3 control lines and a positive bias to select each path. The HMC252QS24 & HMC252QS24E SP6T replaces multiple configurations of SP4T and SPDT MMIC switches and logic drivers.
