摘要
运用统计分析的方法，给出了转发器功放的非线性与交调干扰的关系，可在保证一定信噪比的情况下得到较高的功率利用率．克服了在一般设计中为减少交调干扰，而尽可能提高功率输出动态范围的盲目性。
By using of analytic method of statistics,the relationship between nonlinear feature of power amplifiers and intermodulation is presented in this paper.And higher power utilization coefficient,provided signal to noise ratio is given,can be obtained through the relationship.Meanwhile the deficiency of traditional method of designing by expending dynamic range of power output as wide as possible for the redution of intermodulation is overcome. A new way of designing a wide band tranceiver is put forward by the authors.
