Abstract: Communication is one of the important aspects of human life. With increasing demands of high data rates, carrier aggregation technique will be widely employed in wireless cellular communication. So to support carrier aggregation, it requires multi band transmitters. Due to non-linear characteristics of radio frequency amplifiers, the distortion normally added into the transmitted signal after amplification. The distortion signal not only presented at transmitted bands but also at the intermodulation bands. Finally fall into the received bands leads to huge quality degradation in signals. In order to overcome the transmitter problems there is various techniques proposed. In this paper various compensation models for transmitter leakage in carrier aggregation applications are studied
