    Though the integration of all modes of electrical communication is a practical fait accompli under the progress and aegis of the information theory, the fact remains that there is an undeniable and healthy competition between wire and wireless means in almost all communication fields. I would like to devote this editorial to some aspects of this technical feud, and to be allowed to present some pe... View full abstract»

  • The Characteristic Impedance of a Slotted Coaxial Line

    Publication Year: 1956, Page(s):4 - 8

    The propagation of a second type of TEM mode in a slotted coaxial line is analyzed. The characteristic impedance of the slotted line is evaluated by means of variational expressions giving upper and lower bounds to the true value. A two term approximation to the charge distribution and a one term approximation to potential distribution give results accurate to within +-2 per cent. Curves of charac... View full abstract»

    A new type broadband unidirectional transmission line has been built utilizing the difference in energy distribution between two counter-rotating circularly polarized waves in a circular waveguide containing a ferrite. This principle of isolation is different from those which have been used previously. A large difference is observed in the energy distribution of two counter-rotating TE11 View full abstract»

  • An Approximate Analysis of Coaxial Line with a Helical Dielectric Support

    Shown in Fig. 1 is a cutaway section of coaxial cable with a helical dielectric support. The particular cable depicted bears the trade name of Styroflex derived from the fact that the dielectric helix is built up in a winding operation from nonplasticized polystyrene tapes giving to the final assembly a tight grip on the center conductor and a good degree of allowable bending capability. The outer... View full abstract»

  • Improved Microwave Noise Measurements Using Ferrites

    Publication Year: 1956, Page(s):24 - 28
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (626 KB)

    The ferrite isolator and the ferrite circulator have been applied separately to improve the accuracy of measuring small microwave noise powers or small power differences. Either the isolator or the circulator effectively isolated the input circuit of a microwave receiver from the impedance of the source. As a result, the measurement errors introduced by mismatched source impedances were reduced by... View full abstract»

    A new type of serrated choke will permit cuts or gaps anywhere on the walls of a rectangular waveguide. The low gap impedance is provided essentially by closely spaced, quarter-wave-length, open-ended, two-wire-line stubs. Low power and high power characteristics of many designs are presented.

  • Microwave Filters Utilizing the Cutoff Effect

    Publication Year: 1956, Page(s):36 - 40
    Cited by:  Papers (10)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (465 KB)

    Two band-rejection microwave filters employing the waveguide cutoff effect are discussed. One type utilizes the cutoff property in the series arm of an E plane tee to improve the filter's characteristics, while the other utilizes this property in the E and H arms of a magic tee. Experimental data for both single and multistage filters are presented. Methods of obtaining low standing wave ratios ov... View full abstract»

  • Technique of Pulsing Low Power Reflex Klystrons

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1159 KB)

    Very little published information is available on pulsing low power reflex klystrons. Since low power reflex klystrons have been generally designed for cw operation as local oscillators, a minimum of effort has been directed toward the development of specific low power pulse reflex klystrons. This paper summarizes an effort that has been directed toward pulsing typical low power reflex klystron wi... View full abstract»

  • Determination of the Parameters of Cavities Terminating Transmission Lines

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (242 KB)

    Past methods available for measuring parameters of cavities terminating transmission lines are often considered too involved for production line testing. One common method requires many individual standing wave ratio measurements at frequencies slightly lower and higher than the resonant frequency of the cavity. These measurements take not only an excessive length of time but also require an accur... View full abstract»

    In testing microwave components for electrical breakdown under high power it is generally desirable to simulate conditions encountered in a system. For proper evaluation it is necessary, therefore, to employ a termination, the reflection coefficient of which is variable and which will handle high powers. Our attempt to manufacture a variable mismatch device similar to those described in the litera... View full abstract»

    Dr. Seymour Cohn has pointed out that the equation for attenuation as shown on page four of the article "Double-Ridge Waveguide for Commercial Airlines Weather Radar Installation" by the undersigned should be corrected to read as follows: Using a value for K of 1.2 which seems reasonable for this geometry, Dr. Cohn has computed the attenuation for the double ridge guide and obtained numbers of 0.0...
