HMC245AQS16E v01.0120 GaAs MMIC SP3T Non-REFLECTIVE SWITCH, DC - 3.5 GHz Typical Applications Features The HMC245AQS16 / 245AQS16E is ideal for: Low Insertion Loss: 0.7 dB 2.0 GHz Basestation Infrastructure Non-Reflective Design CATV / DBS Integrated 2:3 TTL Decoder Wireless Local Loop All Off Isolation State Test Equipment Single Positive Supply: Vdd = +5V 16 Lead QSOP SMT Package Functional Diagram General Description The HMC245AQS16E is a low cost non-reflective SP3T switches in 16-lead QSOP surface mount pack- ages. Covering DC to 3.5 GHz, the switch offers 30 to 40 dB isolation and a low insertion loss of 0.7 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. Electrical Specifications, T = +25 C, For TTL Control and Vdd= +5V in a 50 Ohm System A Parameter Frequency Min. Typ. Max.
