| MICROWAVE CORPORATION v01.0404 HMC245QS16 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 GaAs MMIC SP3T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Typical Applications The HMC245QS16 is ideal for: * Basestation Infrastructure * CATV / DBS * Wireless Local Loop * Test Equipment Functional Diagram General Description The HMC245QS16 is a low cost non-reflective SP3T switch in a 16-lead QSOP surface mount package. 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. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, For TTL Control and Vdd= +5V in a 50 Ohm System Parameter Frequency DC - 2.0 GHz DC - 3.0 GHz DC - 3.5 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.5 GHz "On State" DC - 1.5 GHz DC - 3.5 GHz 0.3 - 3.5 GHz 0.5 - 3.5 GHz 0.3 - 2.5 GHz 0.3 - 3.5 GHz 0.3 - 2.5 GHz 0.3 - 3.5 GHz 23 22 44 40 40 35 31 26 Min.
