CHT3091a Ro HS PLIANT DC-40GHz ATTENUATOR Ga As Monolithic Microwave IC Description ..The CHT3091a is a variable DC-40GHz attenuator 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 MESFET process, 0.7µm gate length, via holes through the substrate and air bridges. It is supplied in chip form. Main Features Insertion Loss ( d B ) .
