| HMC245QS16 / 245QS16E v02.0805 GaAs MMIC SP3T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Features Low Insertion Loss: 0.5 dB @ 2.0 GHz Non-Reflective Design Integrated 2:3 TTL Decoder "All Off" Isolation State Single Positive Suppy: Vdd = +5V 16 Lead QSOP SMT Package Typical Applications The HMC245QS16 / HMC245QS16E is ideal for: * Basestation Infrastructure * CATV / DBS * Wireless Local Loop 8 SWITCHES - SMT * Test Equipment Functional Diagram General Description The HMC245QS16 & HMC245QS16E are low cost non-reflective SP3T switches in 16-lead QSOP surface mount packages. Covering DC to 3.5 GHz, the switch offers 30 to 40 dB isolation and a low insertion loss of 0.5 dB. A 2:3 TTL/CMOS compatible decoder is integrated on the switch requiring only 2 control lines and a single +5V bias to select each path, replacing 6 control lines normally required by GaAs SP3T switches.
