HMC241QS16 / 241QS16E v04.0404 Typical Applications Features The HMC241QS16 & HMC241QS16E are ideal for: RoHS Compliant Product • Base Stations & Portable Wireless Low Insertion Loss (2 GHz): 0.5 dB • CATV / DBS Single Positive Supply: Vdd = +5V • Wireless Local Loop Integrated 2:4 TTL Decoder • Test Equipment 16 Lead QSOP Package Functional Diagram General Description The HMC241QS16 & HMC241QS16E are general purpose low-cost non-reflective SP4T switches in 16-lead QSOP packages. Covering DC - 3.5 GHz, this switch offers high isolation and has a low insertion loss of 0.5 dB at 2 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 2:4 decoder is integrated on the switch requiring only 2 control lines and a positive bias to select each path, replacing 8 control lines normally required by GaAs SP4T switches.
