Summary:
An S-band linearizer was developed using GaAs MMIC technology. We call it the even-order-distortion-implemented intermodulation distortion controller (EODIC). EODIC uses even-order intermodulation distortion (IM) components in the second harmonic frequency band to control its IM components in the fundamental frequency band. EODIC is a suitable tool to compensate near-saturated high power amplifiers (HPAs). We developed an EODIC using MMIC technology. This paper describes the principle of EODIC and then introduces the EODIC MMIC in detail. This paper also presents the IM reduction performance of an EODIC in a near-saturated HPA.
