    The design and experimental performance of a wide-band K-band parametric amplifier (paramp) for the experimental domestic satellite communication earth station are described. An optimum idler frequency for a minimum noise temperature is derived taking into account the varactor diode skin effect. Wide-band paramps with a double-tuned signal circuit are discussed and it is shown that triple-tuned ga... View full abstract»

    Experimental results of the 4-port nonreciprocal band-stop-pass filter and the tunable resonance type circulator with the properties of the 4-port filter are reported, and the theory of the new nonreciprocal circuit is discussed. The filter operates over a two-octave frequency range and the over about a one-octave frequency range. View full abstract»

    An unbounded region is divided into local picture-frame regions where a partial differential-equation solution is obtained, with the remaining unbounded region represented by an integral equation. (The method permits the use of free-space Green's functions, and thus special problem-dependent Green's functions need not be found.) The integral equation is formulated as a constraint upon the local pi... View full abstract»

  • Practical Least pth Optimization of Networks

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (568 KB)

    A new and practical approach to computer-aided design optimization is presented. Central to the process is the application of least pth approximation using extremely large values of p, typically 1000 to 1 000 000. It is shown how suitable and reasonably well conditioned objective functions can be formulated, giving particular emphasis to more general approximation problems as, for example, in filt...

  • A Method for Computing Edge Capacitance of Finite and Semi-Infinite Microstrip Lines (Short Papers)

    This short paper describes a method for computing the edge capacitance of finite or semi-infinite sections of microstrip transmission lines. The approach is based on Galerkin's method applied in the Fourier-transform domain. It is mathematically simple and requires the inversion of rather small-size matrices. View full abstract»

  • Intermodulation Characteristics of X-Band IMPATT Amplifiers

    The intermodulation products produced when two equal-amplitude signals are applied to the input of an X-band IMPATT-diode amplifier have been measured. An Si p+nn+ IMPATT diode was operated in a double-slug-tuned coaxial reflection amplifier circuit that was tuned to provide 20 dB of small-signal gain at 9.340 GHz. The intermodulation tests consist of measurements of the magnitudes and frequencies... View full abstract»

  • Design of a Channel Diplexer for Millimeter-Wave Applications

    Publication Year: 1972, Page(s):820 - 827
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (736 KB)

    The design of millimeter-wave filters is, in principle, no different from the design of conventional waveguide filters. In practice, however, several factors impose limitations on the choice of the filter structure. As a result, new filter structures must be used requiring new synthesis techniques for their design. In this paper, a new channel diplexer structure is described and a synthesis techni... View full abstract»

    A nanosecond RADAR system was developed, in which each line of the pulse spectrum was radiated in turn, their reflections measured and stored in a computer, and finally added up to compute the echo. View full abstract»

    A K-band high-power and highly stable power source has been developed using a cavity-stabilized IMPATT-diode oscillator followed by a one-stage high-power reflection-type IMPATT-diode amplifier. The power source shows an output power of 0.7 W, a temperature coefficient of 6x10-7 / °C, and an FM noise level of 92-Hz rms/1-kHz BW at 100 kHz from the carrier. To achieve a highly stable...

    It is shown that, if expansion terms of all the modes appearing in the Green's function for the problem are retained, the singular integral equation method can be made to apply by generating a differential equation for this integral. The solution of the differential equation is straightforward, and the inversion of the resulting integral equation then follows standard methods. The process is appli... 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..
