    Several advantages of multiple-frequency nonlinear reactance circuits are described in this paper. In particular, a circuit is considered in which a nonlinear reactance couples four basic frequencies: ω0, ω12, and ω3; these are so related that ω2 = ω0 + ω1 and ω... View full abstract»

    The paper deals with the problem of three waves, 1, 2, and 3, in which waves 2 and 3 are coupled to wave 1 but not to each other. The general solution for the amplitudes of the waves is given in closed form. It is shown that for certain values of the parameters growing waves can exist. Numerical solutions for the location of the boundaries of the growing wave regions are plotted. It is shown furth... View full abstract»

    The noise figure of the 2K25 reflex klystron amplifier was investigated. The noise figure of the reflex klystron amplifier depends on operating frequency, electronic impedance, circuit impedance, and operating electronic mode. Experimental results show that a noise figure of 5 db is possible under particularly carefully adjusted conditions. In order to obtain the low-noise figure, careful electron... View full abstract»

  • On Measurements of Microwave E and H Field Distributions by using Modulated Scattering Methods

    The modulated scattering method of Justice, Rumsey, and Richmond for measuring E field distribution is extended to the measurement of H field distribution by using a loop scatterer formed by two diodes. This diode loop method has the particular advantage of eliminating the large and undesirable effect produced by the associated E field when measuring the H field. A scattering analysis of the modul... View full abstract»

    Many linear components in nondispersive transmission line are made up solely of commensurate lengths of line of various characteristic impedances. Such components have impulse responses that are a series of equispaced impulses, and, as a result, their frequency responses can be written as a Fourier series. Given the period and coefficients of the Fourier series describing the frequency response, t... View full abstract»

  • Sets of Eigenvectors for Volumes of Revolution

    Publication Year: 1960, Page(s):309 - 319
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (775 KB)

    The electric and magnetic eigenvectors of a volume of revolution can be written in terms of two-dimensional scalar and vector functions. These functions are the eigenfunctions of certain linear transformations in the meridian plane. The form of the transformation is examined, and much attention is devoted to the orthogonality properties of their eigenfunctions and the calculation of their eigenval... View full abstract»

    A novel printed circuit balun is described which is particularly well suited to applications where space is at a premium. The design utilizes unshielded strip transmission line, but is readily adaptable to all of the common printed circuit transmission line techniques. When the balun is housed within the cavity of a spiral antenna, boresight error is virtually eliminated, ellipticity ratios of les... View full abstract»

  • The P-I-N Modulator, an Electrically Controlled Attenuator for MM and Sub-MM Waves

    The construction and performance of a millimeter wave modulator are described. The main part of the modulator consists of a p-i-n germanium structure inserted into a rectangular waveguide. A modulation depth of 11 db could be obtained at frequencies up to 5 kc, this modulation being caused for the greatest part by attenuation. View full abstract»

    A systematic measurements program has been carried out to check the validity of theoretical formulas for the equivalent circuit parameters of a variety of discontinuities in the center conductor of symmetric strip transmission line. These theoretical formulas have been in part previously available and are in part new or modified. Results indicate that, in general, these formulas are adequate for m... View full abstract»

  • A Variational Integral for Propagation Constant of Lossy Transmission Lines

    Publication Year: 1960, Page(s):339 - 342
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (322 KB)

    By assuming that the current on a lossy transmission line flows in the axial direction, only a variational integral for the propagation constant can be readily obtained. This variational integral shows that the usual power loss method of evaluating the attenuation constant is valid for general transmission lines. This variational integral also shows that the perturbation of the loss-free phase con... View full abstract»

  • Measurement of Bandwidth of Microwave Resonator by Phase Shift of Signal Modulation

    Publication Year: 1960, Page(s):343 - 345
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (303 KB)

    Bandwidth is measured by transmission of a signal with sine-wave modulation through a microwave resonator under test. The modulation frequency is adjusted so that the envelope is delayed 45° with respect to the input, indicating that the two sideband frequencies are separated by the half-power bandwidth. The resonance ratio (Q) is then equal to the ratio of carrier frequency over twice the mod... View full abstract»

    Summary--The theoretical approach to the three-port symmetrical circulator is reviewed and presented in a form valid for the most general waveguide case. A strip-line Y-junction circulator is described and the performance of different units in the band 800-1600 mc is illustrated. The new type of device described offers, for the low-frequency region of the microwave spectrum, advantages of simple d... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1340 KB)

    The techniques developed for designing periodically loaded traveling-wave parametric amplifiers using variable-reactance diodes are described in detail. An amplifier was built and tested with two different sets of eight diodes. The performance of the amplifier with each set of diodes agrees substantially with the theoretical predictions, the measured noise figures being about 1.2 db higher than th... View full abstract»

    A chain of identical cavity resonators coupled together through slots in their common walls forms a band-pass microwave filter. The pass band characteristics of such a system are determined by a combination of field theory and circuit theory. The fields in the cavities are expressed in terms of the normal modes of the uncoupled cavities. The fields in the neighborhood of a slot are determined by r... View full abstract»
