High efficient power amplifier with low distortion is required for mobile and broadcasting stations. Predistortion linearizer is one of the practical techniques to reduce the non-linear distortion. The miniature linearizer with a diode has been already reported. The conventional linearizer has the monotonous gain with increase or decrease of input power. In case of class-AB power amplifiers which have a gain expansion, nonlinear distortion is increased by using the conventional linearizer in saturated region. We proposed a Series Anti-Parallel Diode Linearizer(SAPDL). Its gain is decreased in the middle power region and is increased in the saturated region. In this paper, the operation principle of a SAPDL is made clear. We demonstrate that the distortion of the UHF-band power amplifier is reduced with this proposed linearizer.
