CHA2098B - United Monolithic Semiconductors

CHA2098B 20-40GHz High Gain Buffer Amplifier

The CHA2098b is a high gain broadband threestage monolithic buffer amplifier. It is designed for a wide range of applications, from military to commercial communication 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.
