Claim:
1. An apparatus for generating a transmit signal comprising: an up-conversion circuit configured to up-convert a first component signal of a multi-phase baseband transmit signal using a first oscillator signal and up-convert a delayed second component signal of the multi-phase baseband transmit signal using a second oscillator signal to generate a radio frequency transmit signal, wherein the first oscillator signal and the second oscillator signal comprise an oscillator signal phase offset and wherein an edge of the second oscillator signal occurs earlier than a corresponding edge of the first oscillator signal; and a delay circuit configured to delay 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, wherein an edge of the delayed second component signal occurs later than a corresponding edge of the first component signal, and wherein the predefined component signal delay is less than a period of the first oscillator signal.
