    Abstract: An integrated circuit includes a linearizer circuit in which excessive delay is compensated. The linearizer circuit includes a power amplifier, forward and feedback paths, and a microprocessor. A signal from the power amplifier is routed by the forward path to be transmitted while a portion of the signal to be transmitted is routed back to the power amplifier via the feedback path. The microprocessor applies phase training signals to the forward path. The microprocessor uses the phase training signals to determine the amount of delay in the linearizer circuit and alters the frequency position of poles and zeros in the linearizer circuit to compensate for the delay. The gain of the linearizer circuit is also altered by the microprocessor depending on the measured delay.

    Abstract: A communication device, transmitter, and system containing dual quadrature phase shifters and method of training the transmitter are provided. During training, a phase training module determines the phase imbalance in each of in-phase and quadrature Cartesian feedback paths. The phase training module provides control signals to each of in-phase and quadrature dual phase shifters to provide separate and independent phase corrections for the paths. During one training cycle, individual sessions are used to train the in-phase and quadrature dual phase shifters. The latter session uses the results of the former session to provide an initial value for the phase shift to be provided as a result of the latter session, thereby reducing the overall time used to train both the in-phase and quadrature dual phase shifters.
