S-Band 6-bit Digital Phase Shifter
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHP4012-QEG is a 6-bit phase shifter
monolithic circuit, which integrates a CMOS
and TTL compatible interface.
It is designed for a wide range of
applications, typically defence and space
systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is supplied in RoHS compliant SMD
package.
