  1. Vector modulators have been used in this paper to vary the phase and amplitude of signals in the in - band spurious cancellation loop of feed - forward power amplifiers ( ffpa ). in the two - tone test, 3. 5ghz ffpa developed in this paper shows more than 35db improvement in the third - order inter - modulation ( im3 ), offers approximately - 60dbc im3 output, achieves the expected goal, and meets the communication requirement

    本文研製的3 . 5ghz前饋放大器採用了矢量調制器來實現前饋環路的幅度和相位調節,在雙音測試結果中,三階交調im3的改善超過了35db ,前饋系統輸出im3抑制近- 60dbc ,達到了預期指標,滿足了通信需要。
