Filters are an essential part of telecommunications and radar systems and are key items in the performance and cost of such systems, especially in the increasingly congested spectrum. There has been a particularly marked growth in the cellular communications industry in recent years. This has

present an algorithm performing automatic reference plane adjustment. Results obtained on a 10 order dual mode IMUX filter are presented.

This article is a report on experiments investigating the design and construction of microwave filters using metallized plastic substrates and enclosures for commercial aluminum, brass and copper respectively. The cost of metallized ABS plastic substrate may be substantially less than the cost of traditional

and thus potentially increasing functionality of the systems. The aim of this research is to develop electronically reconfigurable microwave filters for future communication systems. The project investigates some key design issues of reconfigurable filters. Circuits were modelled and full

This thesis presents a method for parameter extraction of circuit elements from microwave filters. This diagnosis method can be applied to a su#- ciently large number of filters and it can also be used in conjunction with a neural network model for filter design, greatly reducing development time

Abstract—This paper is an overview of important concepts and formulas involved in the application of coupling coefficients of microwave resonators for the design of bandpass filters with a particular emphasis on the frequency dispersion of coupling coefficients. The presumptions and formulas
