摘要 通过研究多音激励下射频通讯电路三阶无记忆非线性系统的互调失真,得到了多音互调比(IMR)、邻道功率比(ACPR)、噪声功率比(NPR)和同道功率比(CCPR)的理论计算公式,测试结果表明估算公式和实际测试结果的误差在2.56 dB之内。 A generalized approach for evaluation of multitone intermodulation distortion in three order memoryless RF communication circuits is presented in this paper. Theoretical results of multitone intermudulation ratio (IMR),adjacent channel power ratio (ACPR),noise power ratio (NPR) and co-channel power ratio (CCPR) were obtained using multitone signal. The test result indicated that estimated error was less than 2.56 dB.
