  • Tidskriftsartikel (refereegranskat)abstract
    • The partial capacitance approach and conformal mapping techniques are used to evaluate simple closed-form models for parallel and series capacitances of equivalent π-network of a symmetric gap in a CPW. Models are compared with experimental data and full wave analysis. They are useful for a wide range of CPW parameters and frequencies.

  • CAD models for multilayered substrate interdigital capacitors
  • 1996

  • Tidskriftsartikel (refereegranskat)abstract
    • Conformal mapping-based models are given for interdigital capacitors on substrates with a thin superstrate and/or covering dielectric film. The models are useful for a wide range of dielectric constants and layer thicknesses. Capacitors with finger numbers n⩾2 are discussed. The finger widths and spacing between them may be different. The results are compared with the available data and some examples are given to demonstrate the potential of the models

  • Tidskriftsartikel (refereegranskat)abstract
    • Conformal mapping technique is used to obtain CAD oriented closed form analytical expressions for characteristic impedance per unit length capacitance and relative effective dielectric permittivity of top and bottom shielded multilayered coplanar waveguides (CPW). Analytical expressions are deduced for a wide verity of CPW structures

  • Lower order modes of YBCO/STO/YBCO circular disk resonators
  • 1996
  • Ingår i: IEEE Transactions on Microwave Theory and Techniques. - : Institute of Electrical and Electronics Engineers (IEEE). - 0018-9480 .- 1557-9670. ; 44:10, s. 1738 - 1741
  • Tidskriftsartikel (refereegranskat)abstract
    • Lower order modes in a single crystal strontium titanate (STO) circular disk resonator are studied experimentally. Superconducting epitaxial YBCO films form the parallel-plates of the resonator. Due to the extremely high dielectric constant of STO, the electric fields are concentrated between the plates, while there is a substantial magnetic fringing field which affects both the resonant frequencies, Q-factors, and tunability of all modes, especially the TM110 and TM210

  • BROADBAND SMALL SIZE BALUN BUILT WITH LUMPED COMPONENTS
  • 2003
  • Ingår i: Gigahertz 2003 Proceedings. - 0780383311
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This paper reports on a small size broadband lumped element balun suitable for integration in MMICs. The design is an extension of the well known lattice balun, which independent of frequency has 180 degrees phase difference between the output ports, but suffers from a narrow amplitude bandwidth. It is shown how the amplitude bandwidth of the lattice balun may be improved by replacing inductors with low-pass T-sections, and the capacitors with high-pass T-sections. Scalable closed-form design equations for various bandwidths are derived. To validate the concept a prototype operating at 1 GHz has been fabricated with SMT chip components soldered on a PTFE laminate. It exhibits amplitude balance better than +or-0.25 dB and phase balance better than +or-8 degrees , over more than one octave bandwidth. The effective chip-area is 7*9 mm/sup 2/

  • Design of broad-band lumped-element baluns with inherent impedance transformation
  • 2004
  • Ingår i: IEEE Transactions on Microwave Theory and Techniques. - 0018-9480 .- 1557-9670. ; 52:12, s. 2739-45
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper reports on a novel lumped balun topology, the second-order lattice balun, with broad-band performance. The design is based on synthetic transmission lines operating as impedance transformers. The characteristic impedance of the synthetic transmission lines may be chosen to obtain inherent impedance transformation. An analytical investigation results in closed formulas for optimum performance over a given bandwidth. It is shown that it is possible to design for equal ripple in amplitude balance and input reflection coefficient. The phase balance is theoretically perfect over the entire bandwidth. The concept is experimentally validated by a 1-GHz prototype fabricated with surface mounted chip components. It exhibits an amplitude balance better than 0.5 dB and a phase balance better than +or-8 degrees over an octave bandwidth. The effective area of the prototype is 7 * 9 mm/sup 2/
