ABSTRACT:
A digital communication system having a paired power amplifier circuit with two closely matched parallel paths including paired power amplifiers, and drift compensation feedback control loops that control the phase and amplitude characteristics of the paired parallel paths. The phase and amplitude characteristics of the paired parallel paths are monitored and matched to each other in real time. Outputs of the paired power amplifiers are summed together in a power combiner having difference and the sum ports. A transmit conditioner includes a lookup table receives a digital input and generates phase angles for each of the parallel paths. The drift compensation feedback control loops correlate signals derived from the difference and the sum ports of the power combiner to control the phase and the amplitude of carriers in the two parallel paths. Statistical and dynamic compensation may be employed to implement the phase compensation.
