• Conference Proceeding: Microwave breakdown in output multiplexer filters

  [show abstract] [hide abstract]
  ABSTRACT: 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. This study needs a pluridisciplinary approach with a combination of three fields of the science: the electromagnetism, the thermic and the plasma physics

• Conference Proceeding: Improvement of Global Performances of Band-Pass Filters using Non-Conventionnal Stepped Impedance Resonators

  S. Denis, C. Person, S. Toutain, S. Vigneron, B. Theron
  [show abstract] [hide abstract]
  ABSTRACT: 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 over a very large frequency range. New specific synthesis methods are developed to design such filters. Practical investigations are carried out in order to validate the method Furthermore, the proposed method is potentially attractive in various domains, like future multi-standard mobile systems (GSM/DECT) or millimeterwave local communication systems.

• Conference Proceeding: Design and realization of a four pole elliptic microwave filter using low dielectric loaded cavities

  S. Gendraud, S. Verdeyme, P. Guillon, M. Chaubet, J. Sombrin, S. Vigneron, B. Theron
  [show abstract] [hide abstract]
  ABSTRACT: The aim to increase the electrical properties of high power narrow band width filters required for space applications leads us to propose an alternative to classical circular metallic cavities. The introduction of dielectric media in metallic cavities permits to obtain high unloaded quality factor in devices of reduced sizes. An experimental four pole dual mode elliptic filter is constructed using these resonators. The test results are in excellent agreement with the filtering objective

• Conference Proceeding: A new dielectric loaded cavity for high power microwave filtering

  S. Moraud, S. Verdeyme, P. Guillon, Y. Latouche, S. Vigneron, B. Theron
  [show abstract] [hide abstract]
  ABSTRACT: This paper is devoted to high electrical performance filter realization for space application. A new form of new dielectric plate resonator shielded in a metallic cavity is presented. It is suitable for high power applications and presents the advantage to be easily manufactured. The finite element method is applied to design the resonators. Experimental 4 pole quasi elliptic filters have been realized to prove the efficiency of our new technique

• Article: Parallel coupled microstrip filter with phase difference compensation

  S. Denis, C. Person, S. Toutain, B. Theron, S. Vigneron
  [show abstract] [hide abstract]
  ABSTRACT: A new improved design for coupled microstrip filters is proposed. The method is based on a new structure which replaces conventional quarter-wavelength coupled lines. The improvement is achieved by reducing effects due to the difference between the phase velocities of the two normal modes propagated on two symmetric coupled lines. This possibility is demonstrated on a basic cell with the help of analytical formulas

• Conference Proceeding: Complete design for five-pole in line elliptic filter

  Ph. Guillot, H. Baudrand, S. Vigneron, B. Theron
  [show abstract] [hide abstract]
  ABSTRACT: The complete design of a five-pole in line elliptic filter using TE₁₁₃and TM₀₁₂ modes is presented. A multimodal variational method is used in order to determine all iris dimensions and positions. Simultaneous TE/TE and TE/TM mode couplings between the dual and triple mode cavities are provided by a single displaced rectangular iris. A filter has been designed and realized using our theoretical iris dimensions (central frequency: 12.57 GHz and bandwidth 47 MHz). The required and experimental responses are in very good agreement

• Article: Analysis and realization of L-band dielectric resonator microwave filters

  V. Madrangeas, M. Aubourg, P. Guillon, S. Vigneron, B. Theron
  [show abstract] [hide abstract]
  ABSTRACT: High power L -band dielectric resonator microwave filters, used in satellite systems because of their good temperature and vibration characteristics, low weight, and size, are discussed. The electromagnetic and electrical parameters of different microwave dielectric resonator structures are computed by means of the two-dimensional and three-dimensional finite element method, which are applied both for free and forced oscillation systems. The design and response evaluation of an elliptic filter using rectangular dielectric resonators excited in their TM₁₁₀ mode are presented

• Conference Proceeding: A two-step synthesis of broadband ridged waveguide bandpass filterswith improved performances

  J.-C. Nanan, J.W. Tao, H. Baudrand, B. Theron, S. Vigneron
  [show abstract] [hide abstract]
  ABSTRACT: A quarter-wave broadband ridged waveguide bandpass filter with improved stopband attenuation has been designed and realized. A two-step design procedure associating Chebyshev's formulas with a rigorous optimization routine is also presented. The predicted filter performances, including the rectangular to ridged waveguide transformer, agree well with the measurements, showing improved stopband attenuation and reduced filter dimension in the Ku band

• Conference Proceeding: A new finite element method formulation applied to DR microwave filter design

  V. Madrangeas, M. Aubourg, P. Guillon, S. Vigneron, B. Theron, D. Parise
  [show abstract] [hide abstract]
  ABSTRACT: A 3-D finite-element formulation for computing electromagnetic and electrical parameters of microwave dielectric resonator (DR) devices is presented. A comparison of theoretical and experimental results shows the usefulness of the formulation. More accurate results could be obtained by using second-degree NEDELEC polynomials. The results should lead to the realization of a compact high-power bandpass elliptic filter using TM₁₁₀ parallelepiped DR modes, which have low loss and fewer spurious characteristics

• Article: Input impedance and loaded quality factor of a probe exciting dielectric resonator

  S. Vigneron, P. Guillon
  [show abstract] [hide abstract]
  ABSTRACT: Using a dielectric resonator in microwave filter applications, several types of excitations can be considered. An HEM_{11 delta}-mode filter, used in satellite applications, utilises coaxial probes for the coupling of dielectric resonators with the external ports. The authors present the determination of the input impedance and of the coupling parameters between a probe and a dielectric resonator, when the pin is placed in the radial plane of a structure containing a cylindrical dielectric resonator.
