Features
General Description
LOW INSERTION LOSS (1 GHz): 0.6dB
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 1700-2000 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.
See positive bias/TTL SP6T version
HMC252QS24.
