The HMC183QS24 is a low-cost non-reflective SP8T switch in a 24-lead QSOP package for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. A 3:8 decoder is integrated on the switch, requiring only 3 control lines with a negative bias to select an RF path. The 3:8 decoder replaces 16 control lines normally required by GaAS SP8T switches. Switch outputs are terminated when "off". The QSOP24 package occupies the same area as a 14-lead SOIC. See positive bias/TTlL version HMC253QS24.
