| MICROWAVE CORPORATION v02.0101 HMC241QS16 Features Low Insertion Loss (2 GHz): 0.5 dB Single Positive Supply: Vdd = +5V Integrated 2:4 TTL Decoder 16 Lead QSOP Package GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Typical Applications The HMC241QS16 is ideal for: * Base Stations & Portable Wireless * CATV / DBS * Wireless Local Loop * Test Equipment Functional Diagram General Description The HMC241QS16 is a low-cost non-reflective SP4T switch in a 16-lead QSOP package. 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. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, For TTL Control and Vdd = +5V in a 50 Ohm System Parameter Frequency DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.5 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.5 GHz "On State" DC - 2.5 GHz DC - 3.5 GHz 0.3 - 3.5 GHz 0.5 - 2.5 GHz 0.3 - 3.5 GHz 0.3 - 3.5 GHz 0.3 - 3.5 GHz tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 40 150 ns ns 40 32 28 23 17 9 8 12 22 40 Min.
