Abstract :
A linear cascade video amplifier capable of working from DC to about one GHz was designed, fabricated, and initially tested. Two asymmetric SQUIDs operating in push-pull are used to achieve linearity and to eliminate output offset. Decoupling of the Josephson oscilliation between the SQUIDs is accomplished by using a special low-pass resonant transformer. Simulation results are presented for three-and ten-junction SQUIDs.
