"Design of Microwave Filters With Arbitrary Frequency Response Based on Digital Methods,"
by I Arnedo, A. Lujambio, T. Lopetegi, M.A.G. Laso,
in the IEEE Microwave and Wireless Components Letters, vol.17, no.9, Sept. 2007, pp.634-636,

In this paper, a novel method for the design of microwave filters using digital signal processing technique with arbitrary frequency response is presented. It is mainly based on the conversion of the microwave specifications to the digital specification, where the digital filter design technique mainly IIRPNORM algorithm is applied. With the use of digital signal processing techniques, the method calculates the poles and zeros for the analog frequency response that satisfies the given specifications. By the poles and zeros, the microwave filter can be realized using conventional techniques. As an example to demonstrate the proposed technique, a filter with user-defined specifications over two independent passbands has been implemented and this would be tested in microstrip technology.
