Functional Diagram
General Description
The HMC253QS24 is a low-cost non-reflective
SP8T switch in a 24-lead QSOP package featur-
ing wideband operation from DC to 2.5 GHz.
The switch offers a single positive bias and true
TTL/CMOS compatibility. A 3:8 decoder is inte-
grated on the switch requiring only 3 control lines
and a positive bias to select each path. The
HMC253QS24 SP8T will replace multiple config-
urations of SP4T and SPDT MMIC switches.
