Functional Diagram
General Description
The HMC253LC4 is a non-reflective SP8T switch in
a leadless RoHS compliant 4x4 mm ceramic SMT
package featuring wideband operation from DC to
3.5 GHz. The switch offers a single positive bias and
true TTL/CMOS compatibility enabling it to operate
with 0/+3V control and a +5V supply. A 3:8 decoder
is integrated on the switch requiring only 3 control
lines and a positive bias to select each path. The
HMC253LC4 SP8T will replace multiple configurations
of SP4T and SPDT MMIC switches.
