- Passive network is a critical component which is commonly used in electronic and communication device. With the development of digital communication, the demands to the phase frequency characteristics of passive network have become higher and higher, while there is contradiction between the phase frequency characteristics and the amplitude-frequency characteristics. How to get a better group delay characteristics from passband and to gain a larger attenuation from stopband has been the research topic for the relevant national scientists to explore and study. The main solution in the past mainly starts from the network theory. After decades of efforts, the technology has matured, but progressing is very slow. This paper proposes a method that the optimization of passive network element parameters can make the frequency of a phase curve approximate a straight line. The method is firstly to determine a straight line on a phase frequency coordinates as the initial value of the ideal curve. Then to optimize component parameters, making the phase curve approximate this line and to obtain a new element value.
