The general principle of an ultra-wideband (UWB) amplifier design in the planar structure using the common available monolithic amplifier is proposed in this paper. The structure of the amplifier is designed in order to accomplish the conditions of the transmission of UWB impulses (flat gain and constant group delay over FCC approved frequency band) with a minimum distortion. The roll-of stage is used for the compensation of the declining gain and biasing of the monolithic amplifier. The demonstration of the distortion and the assessment criteria of distortion are also presented. The experimentally manufactured amplifier demonstrates a gain of 7.1plusmn0.6 dB and a group delay variation of 7 ps from 4 to 9.3 GH and 25 ps over the whole band.
