Abstract EN
Design of RF and microwave filters has always been the challenging engineering field.
Modern filter design techniques involve the use of the three-dimensional electromagnetic (3D EM) solvers for predicting filter behavior, yielding the most accurate filter characteristics.
However, the 3D EM simulations are time consuming.
In this paper, we propose electric-circuit models, instead of 3D EM models, suitable for design of RF and microwave filters with quasilumped coupled resonators.
Using the diakoptic approach, the 3D filter structure is decomposed into domains that are modeled by electric networks.
The coupling between these domains is modeled by capacitors and coupled inductors.
Furthermore, we relate the circuit-element values to the physical dimensions of the 3D filter structure.
We propose the filter design procedure that is based on the circuit models and fast circuit-level simulations, yielding the element values from which the physical dimensions can be obtained.
The obtained dimensions should be slightly refined for achieving the desired filter characteristics.
The mathematical problems encountered in the procedure are solved by numerical and symbolic computations.
The procedure is exemplified by designing a triple-bandpass filter and validated by measurements on the fabricated filter.
The simulation and experimental results are in good agreement.
