摘要： Systems, apparatus and methods that provide broadband predistortion linearizers including simple frequency desensitizers to maintain substantially the same predistortion in a relatively broad frequency band. For example, a broadband predistorter can include a nonlinear component to predistort the drive signal, and a simple frequency desensitizer to compensate the frequency dependence of the nonlinear component. In particular implementations, the nonlinear component can have a frequency dependent impedance that substantially changes across the broad operating bandwidth and the frequency desensitizer can include resistive and reactive elements, such as a resistor (R), an inductor (L), and a capacitor (C) in a resonator configuration, to compensate for the frequency-dependence of the nonlinear component in the broad operating bandwidth.
