Abstract
A new design topology and performance for the ultra wideband Darlington amplifier is described. The amplifier configuration consists of a common-emitter transistor pair with low-pass filter. The normalized gain characteristic for the amplifier provides 1.36 multiple expansion of frequency band without degradation of the dynamic range, at VSWR and matching of input-output retaining. Expression for the optimum transfer factor was received. On this base the amplifier module for measuring and communication devices is created. This paper will discuss the design theory, techniques, and measurements of this newly developed Darlington circuit.
