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 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 pack-
age occupies the same area as a 14-lead SOIC. See
positive bias/TTL SP6T version HMC252QS24.
