LOW INSERTION LOSS (1 GHz): 0.6dB
INTEGRATED 3:6 DECODER
24 LEAD QSOP PACKAGE
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 ap-
plications. The switch can control signals up to
2.5 GHz and is especially suited for 800-1000
MHz and 1700-2000 MHz basestation applica-
tions. 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 re-
places 12 control lines normally required by
GaAS SP6T switches. Switch outputs are
reflective shorts when "off". The QSOP24 pack-
age occupies the same area as a 14-lead SOIC.
