20090146740 | Average power efficiency enhancement and linearity improvement of microwave power amplifiers - A biasing circuit is used to provide low distortion and high efficiency operation of a microwave power amplifier. The biasing circuit utilizes the nonlinear rectified current of a microwave diode or transistor for biasing the amplifying transistor self-adaptively. The biasing current not only reduces the DC bias power during low-power operation and increases self-adaptively during high-power operation, but also manipulates the intermodulation distortion minimum dynamically. Meanwhile, the biasing circuit distorts the input signals with positive gain and negative phase deviations. Therefore, the average power efficiency of the operation is enhanced, the linearity of the input-output characteristic is improved and the radiated level of adjacent channel power is suppressed. | 06-11-2009 |
