United Monolithic Semiconductors CHX2091-99F-00 Datasheet
20-40GHz Frequency Multiplier
GaAs Monolithic Microwave IC
Description
The CHX2091 is a cascadable by 2 frequency
multiplier monolithic circuit.
It is designed for a wide range of applications, from
military to commer cial comm unication systems. The
backside of the chip is both RF and DC grounds.
This helps simplify the assembly process.
The circuit is manufactured with a PM-HEMT
process, 0.25µm gate length, via holes thr ough the
substrate, air bridges and electron beam gate
lithography.
Main Features
