GaAs MMIC SP4T SWITCH NON-REFLECTIVE DC-2 GHz FEBRUARY 1998 Features General Description LOW INSERTION LOSS: 0.8dB The HMC182S14 is a low-cost terminated SP4T switch in a 14-lead SOIC package for use in antenna diversity, switched filter 14 LEAD SOIC PACKAGE banks, gain/attenuation selection, and gen- eral channel multiplexing applications. The switch can control signals up to 2GHz andis especially suited for 800-1000MHz basestation applications. A 2:4 decoder is integrated on the switch, requiring only 2 control lines and a negative bias to select each RF path. The 2:4 decoder replaces 4 to 8 control lines normally required by GaAs SP4T switches. The HMC182S14 is a drop- in replacement for the HMC 165814 in appii- cations requiring low off state" VSWR.
