| dc.description.abstract | In this paper, an analog linearizer using second harmonic signals feedforwarding is proposed. The harmonic generator of the proposed linearizer that consists of a small signal amplifier extracts second harmonic signals. A vector modulator, modulate fundamental signal with second harmonic signals, makes the inverse third order intermodulation distortion (IMD3) signals of power amplifier and controls amplitude/phase of them with modulation factors. As a result, this linearizer is suppressed IMD3 signals of power amplifier effectively. The test results show that IMD3 signals of power amplifier are suppressed more than 20dB for CW two-tone signals. Also, it’s improved the adjacent channel power ratio (ACPR) more than 7dB for CDMA (IS-95) signals. | en |
