    Abstract: A method and an apparatus for calibration of a transmitter not having a Surface Acoustic Wave (SAW) filter are provided. The apparatus includes a calibration unit for outputting a detuning signal by which a resonance frequency of a Radio Frequency (RF) circuit is detuned with respect to a transmit operating frequency, and an RF unit for changing the resonance frequency according to the detuning signal and for outputting an out-of-band noise and a transmit signal having a relatively lower power than that of a case where the resonance frequency and the transmit operating frequency are tuned to each other.
