    In this paper, we compare the measured and theoretical performance of a room-temperature single-ended Schottky diode mixer in the WR-5 (140-220-GHz) waveguide band. Using the computer program GISSMIX, combined with measurements made on a 100X scale model of the WR-5 mixer, we have been able to predict the millimeter-wave mixer performance over a wide tuning range with unprecedented accuracy.

    Fundamental-mode Pierce oscillators in the 250-300-MHz range have been realized utilizing a unique form of a bulk-acoustic-wave (BAW) resonator. Phase noise greater than -100 dBc/Hz (1-kHz offset) has been extrapolated from data collected on oscillators operating at -22 and -24 dBm. Higher power levels to +6 dBm have been achieved. A linear-model design was used. The circuit topology used and reso... View full abstract»

    Cited by:  Papers (75)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (560 KB)

    A method of analysis is proposed for characterizing finline discontinuities. Two conducting or magnetic planes are inserted at some distances away from the discontinuity so as to obtain a closed resonant structure. A transverse resonance technique is then used to compute the resonant frequencies and, from these, the equivalent circuit parameters of the discontinuity. In the particular case when th...

    LSE and LSM fields in generalized planar guiding structures are shown to be coupled only by means of the edge condition, which can be fulfilled as the final step in the analysis. This is utilized by applying the singular integral equation technique to finlines. Modes up to the thirtieth are thus easily and quickfy computed. View full abstract»

    A planar structure having arbitrarily located conductor lines immersed in complex anisotropic media presents one with a very general guided wave problem. This problem is solved here by a rigorous formulation technique characterizing each layer by a 6 x 6 tensor and finding the appropriate Fourier transformed Green's function matrix G of 2n x 2n size. From G, a method-of-moments solution for the pr... View full abstract»

    The theme of the 1984 MTT-S International Microwave Symposium was "Expanding Microwave Horizons." The conference theme was a most appropriate one. Today's working engineers need to stretch their thinking, but in some nontechnical directions, because the factors most crucial to their success--and their industry's future--are not solely or even primarily technical in nature.

    The theory of TEM matching sections has been modified so that it can be applied to finline tapers. A step-by-step procedure is given to calculate the taper contour for a given maximum VSWR. The taper is optimum in the sense that its length is the shortest possible for the required VSWR. To achieve fast convergence, a transversal resonance method was developed to calculate finline dispersion, which... View full abstract»

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..
