Low Insertion Loss (2 GHz): 1.3dB
Single Positive Supply: Vdd = +5V
Integrated 3:8 TTL Decoder
24 Lead QSOP Package
General Description
The HMC253QS24 & HMC253QS24E are low-cost
non-reflective SP8T switches in 24-lead QSOP
packages featuring 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 integrated on the switch requiring only 3 control
lines and a positive bias to select each path. The
HMC253QS24 & HMC253QS24E SP8T will replace
multiple configurations of SP4T and SPDT MMIC
switches.
