A Method to Achieve Transmission Zeros Based on Coaxial Cavity Filters
Yang Liu · Journal of Hubei University of Education · 2011
Nowadays,the low-cost,small size,low insertion loss,high-performance narrowband filters is widely used in communication systems.Chebyshev filter can not meet these high requirements,elliptic function filter? is difficult to achieve and debugging.Taking into account these problems,Quasi-elliptic function filter which has transmission zeros and high-performance narrowband is now being used in some special situations.How to design this filter is a complicated question,and this article will focus on ways to increase the transmission zeros during the design of the Coaxial cavity filters.
