HMC183QS24 / 183QS24E v02.0805 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 2 GHz Typical Applications Features The HMC183QS24 / HMC183QS24E is ideal for: Low Insertion Loss (1 GHz): 0.8dB • Basestation Infrastructure Integrated 3:8 Decoder 24 Lead QSOP Package Functional Diagram General Description The HMC183QS24 & HMC183QS24E are low-cost non-reflective SP8T switches in 24-lead QSOP packages 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/TTL version HMC253QS24.
