摘要
用信号流图法直接计算了带通滤波器(BPF)的传输系数S_(21)。采用Powell法编制了鳍状线BPF的优化设计程序。实验表明,用此方法比用常规的K-变换器法制成的滤波器性能更接近预给的技术指标。
The transmission coefficient s_(21) of BPF is calculated directly using the signalflow graph method. An optimum design program for fin-line BPF based on Powell'smethod is drawn up. Experiments show that the practical performances of the fin-lineBPF are closer to the predicted values when the optimum method instead of theconventional K-inverter method is adopted.
