GaAS MMIC SP6T SWITCH DC TO 2.5 GHz

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.
