Transmitter with delay mismatch compensation

摘要

A transmitter device comprises a digital part and an analog part. The digital part comprises a digital modulator for receiving bits and for digitally modulating the received bits. The transmitter device includes first and second digital-to-analog converters. The transmitter device furthermore comprises at least one filter unit arranged in the digital part and coupled between at least one of the first and second digital-to-analog converters and the digital modulator. A table unit is coupled to the at least one filter unit and is used to store pre-defined compensation filter values for the at least one filter unit to compensate different delay mismatches in the analog part of the transmitter device. The filter values of the at least one filter unit are set to those compensation filter values as stored in the table unit (TU) which correspond to a determined delay mismatch.
