APPARATUS AND METHOD FOR GENERATING A TRANSMIT SIGNAL

摘要

An apparatus for generating a transmit signal includes an up-conversion module and a delay module. The up-conversion module up-converts a first component signal of a multi-phase baseband transmit signal using a first oscillator signal and up-converts a delayed second component signal of the multi-phase baseband transmit signal using a second oscillator signal to generate a radio frequency transmit signal. The first oscillator signal and the second oscillator signal comprise an oscillator signal phase offset so that an edge of the second oscillator signal occurs earlier than a corresponding edge of the first oscillator signal. The delay module delays a second component signal of the multi-phase baseband transmit signal relative to the first component signal of the multi-phase baseband transmit signal by a predefined component signal delay to generate the delayed second component signal of the multi-phase baseband transmit signal.
