This article describes a basic building block for microwave waveguide filters. It uses a new coupling scheme where all resonant modes are used at their cutoff frequency. It is composed of a cascade of basic nonloaded rectangular cavities where the mo

A theoretical investigation is made of microwave breakdown in output multiplexer filters. The effects of the electrical breakdown cause irreversible damage to the device and so the power level, which generates such a phenomenon, must be predicted. Th

In this paper, we propose the use of non-conventionnal stepped impedance resonators to built high performance band-pass filters. Particularly, we show that it is possible to improve the control of spurious responses outside of a selected bandwidth ov

Monolithic transversal and recursive microwave active filters overcome the, drawback of heavy resonant elements and lack of operational amplifiers in high frequencies domain. We present a GaAs transversal MMIC filter centred at 11.7 GHz. The experime

In order to minimize the mass and the volume of the equipments of satellites payloads, a high power bandpass filter using square cross dielectric resonators excited on the TM110 mode has been developped and tuned. The resonator has a high unloaded qu
