【発明の名称】抵抗性結合器および分圧器を有する先行歪ませ等化器
Document Type and Number:
Japanese Patent JP3041805
Kind Code:
B2
Abstract:
A predistortion equalizer for a power amplifier includes a linear channel and a nonlinear channel. A phase shifter is associated with the linear channel and an attenuator is associated with the nonlinear channel. A resistive power divider divides the received signal which is to be predistorted and divides it into two parts, each of which is applied to one of the channels. The two parts may be equal in magnitude. The linear and nonlinear signals at the outputs of the linear and nonlinear channels, respectively, are combined out-of-phase in a resistive combiner to produce a predistorted signal for appication to a power amplifier. The resistive combiner and divider maximize bandwidth.
