本文利用LCX综合法与模式搜索最优技术,建立了一个用计算机辅助调谐微波滤波器十分有效的方法。根据反射系数相位的测量结果,算出被测短路网络的腔间耦合系数和谐振腔的失谐系数。该方法成功地用于调谐既有椭圆衰减峰值又有群延迟均衡的六极点滤波器,且看来对用于多路多工器的频道滤波器统调也颇有希望。
In this paper, using the LCX synthesis method and pattern search optimization techniques, a computer-assisted tuning microwave filter is very effective method. According to the measurement results of the reflection coefficient phase, the cavity-to-cavity coupling coefficient of the short-circuited network and the detuning coefficient of the resonator are calculated. This method has been successfully used to tune six-pole filters with both elliptic attenuation peaks and group delay equalization, and appears promising for channel filter tuning for multiplexed multiplexers.
