Abstract

In this paper, a new type of linearizer using a parallel diode with a bias feed resistance has been studied. It has positive gain and negative phase deviations because of a nonlinearity of the diode and movement of bias point cause by a voltage drop at the bias feed resistance. This predistortion linearizer consists of the little component and miniaturizes circuit design. The characteristics of this linearizer can be easily tuned using input bias voltage. In fabricated linearizer, maximum gain and Phase deviation of the linearizer is 1dB, 21$^{\circ}$ respectively. By applying its characteristics to the power amplifier, it will be linearized power amplifier.
