Abstract :
The authors describe the distortion compensation characteristics of a transistor-type pre-distortion circuit for private mobile radio, and how third-order intermodulation distortion (IMD3) near the saturation point (38.3 dBm of output power) could be improved by 12.2 dB by employing a phase inverter with passive elements
