HMC244G16 v02.1105 Typical Applications Features The HMC244G16 is ideal for: Low Insertion Loss: 0.7 dB • Telecom Infrastructure Non-Reflective Design • Military Radios, Radar & ECM Integrated 2:4 TTL Decoder • Space Applications Single Positive Suppy: Vdd = +5V • Test Instrumentation 16 Lead Hermetic SMT Package Functional Diagram General Description The HMC244G16 is a non-reflective SP4T switch in a 16 lead glass/metal (hermetic) package. Covering DC to 4.0 GHz, the switch offers 30~50 dB isolation and a low insertion loss of 0.7 dB through 3 GHz. A 2:4 TTL/CMOS compatable decoder is integrated on the switch requiring only 2 control lines and a positive 5V bias to select each path, replacing 8 control lines normally required by GaAs SP4T switches.
