New type of mixed modes dielectric cavity filter for multiplexers

17th AIAA International Communications Satellite Systems Conference and Exhibit, 1998
A new configuration of mixed mode cavities is shown to be the basic building block in advanced filter designs providing the realisation of arbitrary filter functions with low loss and excellent spurious performance. It demonstrates the utilisation of dual or multi mode cavities without the need of coupling discontinuities (e.g.

Mixed modes cylindrical planar dielectric resonator filters with rectangular enclosure

IEEE Transactions on Microwave Theory and Techniques, 1995
A compact mixed modes cylindrical planar dielectric resonator filter in rectangular enclosure with excellent spurious free performance is presented. Space coupling between different mode's dielectric resonators and iris coupling between identical mode's dielectric resonators are realized in the filters.

Mixed-mode automatic tuning scheme for high-Q continuous-time filters

IEE Proceedings - Circuits, Devices and Systems, 2000
An automatic tuning scheme using envelope detectors and simple mixed-mode circuitry is discussed. The method is developed especially for filters with large Q values and can be used at very high operating frequencies. The circuit was designed in a 1.2 µm CMOS process with a 3 V single supply voltage.

Self-Shielded Single- and Dual-Band Quad-Mode Substrate Integrated Waveguide Bandpass Filters Based on Mixed-Mode Cavity

IEEE Transactions on Circuits and Systems Part 1: Regular Papers
In this paper, self-shielded quad-mode substrate integrated waveguide (SIW) bandpass filters (BPFs) are proposed by using a novel method of mixed-mode cavity, which is achieved by adding a metal patch to the middle substrate layer in a SIW cavity.

Dual Band Dual Mode Substrate Integrated Waveguide Filter With Mixed Coupling

IEEE Microwave and Wireless Technology Letters
This letter presents a dual-band substrate integrated waveguide (SIW) filter based on the dual modes of TE101 and TE102 in multilayer structures. Its middle metal layers feature mixed-coupling structures, where the slots implement independent magnetic ...
