6-18GHz Phase-shifter
GaAs Monolithic Microwave IC
Description
The CHP4511 is a 4-bit digital phase-
shifter with an output single pole double
through (SPDT) switch. It is designed for 6
to 18GHz frequency range applications.
The backside of the chip is both RF and
DC grounded.
The circuit is manufactured with a Power
PHEMT process, 0.25µm gate length, via
holes through the substrate, air bridges
and electron beam gate lithography.
It is available in chip form.
