Optimum topology for power handling in dual bandpass filters

由于对容量的需求不断增加，部署在蜂窝基站的射频滤波器的典型滤波要求特别严格。这种高性能滤波器需要估计其功率处理能力，以避免故障。研究射频滤波器网络拓扑结构中的储能分布是估计其功率处理能力的一种方法。给定传递函数的总时间平均存储能量是常数。然而，它的分布受到综合网络拓扑结构的强烈影响。本研究的目的是使用模式识别算法来寻找实现单波段和双波段传递函数的滤波器网络中存储能量分布的相似性。通过找到这样的相似性，可以推导出对于给定传递函数估计最优网络拓扑的准则。

Due to the ever-increasing need for capacity, the typical filtering requirements for RF filters deployed at cellular base stations are particularly stringent. Such high performance filters require estimation of their power handling capacity to avoid breakdown. Investigation of the stored energy distribution in network topologies of RF filters is one approach to estimating their power handling capacity. The total time-averaged stored energy for a given transfer function is constant. It's distribution, however, is strongly influenced by the synthesised network topology. The aim of this research is to use a pattern recognition algorithm to find similarities in the stored energy distribution within filter networks realising single and dual band transfer functions. By finding such similarities, guidelines for estimating the optimum network topology for a given transfer function are to be deduced.
