HMC172QS24

v01.0101 HMC172QS24 GaAs MMIC SP6T SWITCH DC - 2.5 GHz Features Low Insertion Loss (1 GHz): 0.6 dB Integrated 3:6 Decoder 24 Lead QSOP Package Typical Applications The HMC172QS24 is ideal for: • Basestation Infrastructure Functional Diagram General Description The HMC172QS24 is a low-cost SP6T switch in a 24-lead QSOP package for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. The switch can control signals up to 2.5 GHz and is especially suited for 800-1000 MHz and 17002000 MHz basestation applications. A 3:6 decoder is integrated on the switch, requiring only 3 control lines and a negative bias to select each RF path. The 3:6 decoder replaces 12 control lines normally required by GaAs SP6T switches. Switch outputs are reflective shorts when “off”. The QSOP24 package occupies the same area as a 14-lead SOIC.
