摘要
推导并分析了存在增益和相位跟踪等误差情况下,功率放大器前馈技术对三阶线性失真的改善情况,并从原理上论述了前馈技术的工作原理。前馈技术一般可将三阶互调降低10-30 dB,在新一代的抗干扰跳/扩频电台中有广泛应用。
The improvement of the power amplifier feed forward technique to the IMD （ Inter - modulation Distortion） with errors in gain and phase tracking is analysed. The working principle of feed forward technique is discussed. With the technique ,the performance in IMD can be improved by 10- 30dB, and it will be useful in the application of new generation anti -jamming DS/FH radios.
