    High-frequency small-signal circuit parameters are evaluated for a saturated-channel MESFET by including transit-time effects in a rigorous way through a study of induced shape changes in the saturated-channel region. Results agree well with empirical equivalent-circuit parameters for a physical MESFET. View full abstract»

    The cylindrical cavity dual orthogonal transverse magnetic (TM) mode is introduced as a basic building block for the realization of microwave multiple-coupled-cavity bandpass filters. This concept is shown to offer significant advantages in the design of triple-mode filters and permits the design of the new quadruple-mode filter. Experimental verification is provided by the realization of a triple... View full abstract»

    The measured performance of acoustic charge transport (ACT) based linear FM dispersive delay line filters is presented and compared to modelled performance. The excellent agreement between the theoretically predicted device performance and the measured results shows clearly that anodization of the nondestructive sensing array is an effective means for achieving weighted ACT filter responses.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (816 KB)

    The design of microwave integrated circuits requires accurate simulation tools capable of predicting a variety of nonlinear distortion effects, including gain compression and intermodulation distortion. This paper uses the recently developed generalized power series analysis to simulate a MESFET amplifier. The simulations are in agreement with experimental results for single-tone and two-tone inpu... View full abstract»

    A method for the rigorous calculation of the coupling coefficient between dielectric resonators excited in non-axially symmetric hybrid modes is developed. A simplified model is derived which allows approximate accurate calculations of coupling, without solving the detailed boundary value problem. Experimental measurements of the coupling between the two lowest hybrid modes were performed to verif... View full abstract»

    A bandstop filter realized by means of rectangular resonators coupled to the center dielectric strip of a nonradiative dielectric (NRD) waveguide is described.This filter has the advantage that it is simple to manufacture, making use of a center dielectric of standard cross section. The design procedure is similar to the conventional strip line design procedure, with the stubs replaced by "stubs" ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (640 KB)

    An adaptive scheme is proposed to generate the spectral response of waveguide junctions in minimum computation time. The procedure uses the newly developed transfinite element method to determine the fields in junctions at a, few adaptively selected frequencies and then employs these solutions to generate the spectral response throughout the frequency range of interest. In typical problems, the me... View full abstract»

  • Canonical and Longitudinal Dual-Mode Dielectric Resonator Filters Without Iris

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (776 KB)

    Two bandpass filter realizations using dual-mode dielectric resonators in simple tubular enclosures are described. The new configurations do not require iris to achieve the couplings among the resonators. This eliminates the need for the most expensive machined parts of the filters, which require tight tolerances. The realizations also achieve lower midband insertion losses than comparable filters...

Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
