DEVICE AND METHOD FOR COMPENSATING PHASE DISTORTION |
摘要 |
The present invention relates to a method of compensating for the phase distortion that occurs in a power amplified output signal in response to the output power of a power amplifier. The invention also relates to a phase distortion compensating device. The device includes a phase-locking and upconversion loop (30-39) which is connected to the input of a power amplifier (40). Briefly, the solution involves feeding a part of the signal (e pha) to be amplified back to a circuit (35) which combines this first mentioned signal with a part of the amplified signal (e out) fed back from the output of the power amplifier (40), so as to achieve a smooth transition in the dominance of one signal over the other signal when the two signals are combined to obtain a new feedback signal (e fdb) from the combining circuit (35).
