“…Unlike the previous papers [1][2][3][5][6][7], in the given study a new condition of phase shift minimum at attenuation changing for the linear attenuator with adjusting circuits is determined. It is possible a new design of phase invariant attenuator based on this condition.…”

“…The most spreading elements are FETs and diodes with small parasitic parameters, in particular, p-i-n diodes, which parasitic reactances provide the growing of attenuation with frequency increase, and consequently, to reduction of transfer factor. Therefore the phase shift cannot be reduced more than up to 2-5 degrees [5].…”

A necessary condition for minimum of the phase shift vs. attenuation in a voltage controlled attenuator (VCA) is founded on the base of the linear system theory. The condition consists of equality of numerator and denominator polynomial degrees for the transfer function. Also the paper discloses details of the new VCA structure based on the cross-coupling circuits and discusses its performance. Its main difference from known consists in ultra wide band feature and large range of attenuation, where minimum of the phase shift is provided. As a result, the output parameters and adjusting parameters of diodes are founded.Index terms -Attenuator linear model, low phase shift, phase invariance, voltage controlled attenuator.
