CHA2098B
CHA2098B is 20-40GHz High Gain Buffer Amplifier manufactured by United Monolithic Semiconductors.
Description
The CHA2098b is a high gain broadband threestage monolithic buffer 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 P-HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
