    • The present invention provides a feed-forward amplifier having a predistortion circuit to provide a sufficient compensation for a variation in temperature. When a predistortion circuit 3 is used to minimize distortion in a main amplifier 6, the circuit 3, a variable attenuator 4, a variable phase shifter 5, and a main amplifier 6 are located in this order and a control circuit 19 controls the variable attenuator 4 and variable phase shifter 5 so that a carrier component, that is, an input signal, in a detected distortion component decreases to a minimum. In this manner, when the gain of the main amplifier 6 varies due to a variation in temperature, the preceding variable attenuator 4 and variable phase shifter 5 compensate for the variation of the gain. The input level of the predistortion circuit 3, however, is not affected, so the relationship between the output levels of the predistortion circuit 3 and main amplifier 6 remain unchanged compared to the amount prior to the temperature variation, thereby providing the same compensation effect.
    • 本发明提供一种具有预失真电路的前馈放大器,以提供对温度变化的足够补偿。 当使用预失真电路3来使主放大器6中的失真最小化时,电路3,可变衰减器4,可变移相器5和主放大器6按此顺序定位,并且控制电路19控制可变衰减器 4和可变移相器5,使得检测到的失真分量中的载波分量,即输入信号降至最小。 以这种方式,当主放大器6的增益由于温度变化而变化时,前一可变衰减器4和可变移相器5补偿增益的变化。 然而,预失真电路3的输入电平不受影响,因此预失真电路3和主放大器6的输出电平之间的关系与温度变化之前的量保持不变,从而提供相同的补偿效果。
