CHP2085
S-band Phase Shifter / Switch
GaAs Monolithic Microwave IC
Description
The CHP2085 is a S-band monolithic
5 bits phase shifter / switch.
The circuit is manufactured with a
standard MESFET process : via holes
through the substrate, air bridges and
electron beam gate lithography.
It is supplied in chip form.
