Abstract

PURPOSE:To secure the gain frequency over a wide range, by matching the output side of the final-step amplifier and the input side of the first-step amplifier of the microwave multi-step amplifier to the characteristic impedance, for example, to 50OMEGA and then setting the matching between the amplifier steps to the optimum characteristic impedance.
