GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 3.5 GHz
Features
Ceramic, RoHS Compliant 4x4mm SMT Package
Non-Reflective Topology
Low Insertion Loss: 1.2 dB
Single Positive Supply: Vdd = +5V
Integrated 3:8 TTL/CMOS Decoder: 0/+3V
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.
