摘要： An amplifier circuit responsive to a power mode signal improves efficiency at low power levels without compromising efficiency at high power levels. At low power levels, high impedance is presented with suitable adjustment in the phase of the signal. Also, providing for predistortion linearization improves high power efficiency and switching the predistortion linearizer OFF at low power levels contributes little more than a small insertion loss. The power amplifier also uses a bias circuit incorporating a dual harmonic resonance filter to provide high impedance at a fundamental frequency and low impedance at a second harmonic. These properties are of particularly advantageous since amplifiers in cell-phones are used in low power modes most of the time although they are designed to be most efficient at primarily the highest power levels.

摘要： The present invention uses an AC signal and an external DC control voltage to generate a plurality of levels of output DC voltages. The level of the output voltage is determined by the DC control voltage and has the opposite polarity. The invention is preferably implemented as a balanced circuit, which generates spurious signals at even harmonics of the AC frequency signal. The spurious signals can then be filtered out using a low-pass filter.
