Planar thick film frequency filter design

Abstract

This article deals with thick film frequency filter design, its manufacturing and properties. The technology of thick-film is widely used in military or industrial, because of possibility to manufacture cost-effectively prototypes and small series [1]. The civil using includes railway transport, where this is the main part of communication modules (e.g. duplexers), where serves for splitting of transmitted and received signal [2]. This paper describes design for the thick-film manufacturing process and discusses the manufacturing possibilities.
