CHA2097A
CHA2097A is 20-40GHz Variable Gain Amplifier manufactured by United Monolithic Semiconductors.
Description
The CHA2097a is a variable gain broadband threestage monolithic amplifier. It is designed for a wide range of applications, from military to mercial munication 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 through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
