    The following is a brief description of the basic principles and applications of the parametron, which is a digital computer element invented by the author in 1954. A parametron element is essentially a resonant circuit with a nonlinear reactive element which oscillates at one-half the driving frequency. The oscillation is used to represent a binary digit by the choice between two stationary phase... View full abstract»

  • Microwave Parametric Subharmonic Oscillators for Digital Computing

    In a digital information handling system, a binary one can be represented by an RF signal of a given phase, frequency, and amplitude, and a binary zero by RF of the same frequency and amplitude but with opposite phase. The use of subharmonic oscillators to switch, store, and amplify binary information coded in this manner is reviewed. A variable capacitance subharmonic oscillator having an output ...

  • The Radiansphere around a Small Antenna

    The "radiansphere" is the boundary between the near field and the far field of a small antenna. Its radius is one radianlength (¿/2¿), at which distance the three terms of the field are equal in magnitude. A "small" antenna is one somewhat smaller than the radiansphere, but it has a "sphere of influence" occupying the radiansphere. The power that theoretically can be intercepted by a hypothetica...

  • Voltage Breakdown Characteristics of Microwave Antennas

    The problem of voltage breakdown and its effects is discussed for a pulse antenna system. Voltage breakdown occurs at power levels when the pressure is reduced. The minimum breakdown potential occurs approximately at the pressure where the frequency of collision between electrons and gas atoms is equal to the frequency of the applied field. Experiments were made to determine the power levels requi... View full abstract»

  • Some Broad-Band Transformers

    Several transmission line transformers are described which have bandwidth ratios as high as 20,000:1 in the frequency range of a few tens of kilocycles to over a thousand megacycles. Experimental data are presented on both transformers and hybrid circuits. Typical applications are: interstage transformers for broad-band amplifiers; baluns for driving balanced antennas and broad-band oscilloscopes;... View full abstract»

  • Dissipation Loss in Multiple-Coupled-Resonator Filters

    This paper examines the effect of dissipation on the response of multiple-coupled-resonator filters designed from lossless prototype low-pass filters. A simple approximate formula makes possible the computation of center-frequency loss in terms of bandwidth, unloaded Q of the resonators, and the parameters of the prototype filter. It is shown how the insertion loss elsewhere in the pass band and s... View full abstract»
