    With this issue, the PGMTT embarks on a new publication policy. For our regular issues, which will be published in January, April, July and October, we will use the same style type and format used in the Proceedings. Periodically, we will publish such special issues as appear necessary to keep us well informed. The first of these will be the Special Issue on the Microwave Strip Circuits Symposium ...

    Born at Little Cooley, Pennsylvania, on August 24, 1890, Dr. Southworth did undergraduate work at Grove City College and graduate work at Columbia and Yale. Then for ten years he was a teacher and for many more years a research worker on the various frequency frontiers of radio. Beginning with experimental work at Grove City College prior to World War I and continuing with research work at the Bur... View full abstract»

    There are still many people who remember well when radio was used solely for telegraph purposes. At that time there was no broadcasting, no transoceanic telephony and, of course, no television or radar. Nor were there any of the countless other services now rendered by radio, such as telephone communications with airplanes and with motor vehicles. Beginning back in the early days of radio with the... View full abstract»

  • A Method of Forming a Broad-Band Microwave Frequency Spectrum

    Publication Year: 1955, Page(s):4 - 9

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (586 KB)

    A method of generating a wide spectrum of evenly spaced sidebands in the microwave region, suitable for use as a frequency standard, is presented and discussed. The frequency spectrum is produced by modulating the beam acceleration voltage of a klystron with two high-frequency voltages. The frequency of one of these modulation voltages is an integral multiple of the frequency of the other voltage,... View full abstract»

  • A Turnstile Polarizer for Rain Cancellation

    Publication Year: 1955, Page(s):10 - 15
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2315 KB)

    This paper describes a rain canceller using a turnstile junction to provide the necessary polarization of the fields. It discusses the system from the point of view of adapting an existing radar feed system to one that will permit the reduction of rain return. The turnstile junction is described, and it is shown to have properties that meet the requirements for obtaining circular or elliptical pol... View full abstract»

    Some well known principles of filters and transmission lines are recalled and used to develop graphical methods of analyzing Iossless transmission line filters consisting of a series of symmetrical and identical sections. The results of this development are used to construct a special filter analysis chart by means of which a filter may be completely analyzed from a Smith Chart plot of the input i...

  • A Waveguide Impedance Meter for the Automatic Display of Complex Reflection Coefficient

    Publication Year: 1955, Page(s):22 - 30
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1333 KB)

    A waveguide impedance meter has been developed, comprising some specially designed components and some components previously designed for other applications. When this circuit is used in conjunction with the X-band rapid sweep oscillator and suitable display and control circuits, the impedance focus of a waveguide component is automatically and rapidly measured and oscilIographically displayed in ...

  • A Method of Measuring Dissipative Four-Poles Based on a Modified Wheeler Network

    Publication Year: 1955, Page(s):30 - 36

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (702 KB)

    A method of abstracting the parameters of dissipative four-poles from measured data is presented here. This semi-precision method is applicable to symmetric four-poles and results directly in a conveniently symmetric network representation. It is based on the modified Wheeler representation, a new and completely general network, which is introduced in this paper. In addition to the derivation of t... View full abstract»

  • Notes on a Crystal Mixer Performance

    Publication Year: 1955, Page(s):37 - 39
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (266 KB)

    A simple relation between optimum rf source impedance for minimum noise figure and the nominal conversion loss of a mixer is derived. This impedance is related to the input mismatch and its dependence on the type of IF amplifier input circuit is discussed. Relations between the crystal noise temperature and mixer noise temperature as a function of conversion loss are derived for different load con... View full abstract»

  • Intrinsic Insertion Loss of a Mismatched Microwave Network

    Publication Year: 1955, Page(s):40 - 45
    Cited by:  Papers (13)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (605 KB)

    A brief review is presented of the absolute minimum loss of a two-port, mismatched lossy microwave network. This minimum loss, called the "intrinsic insertion loss" can be attained by adding suitable susceptances at the ports that will yield simultaneous bilateral network match. A measurement procedure is described and convenient graphs are presented. View full abstract»

    In my paper "Crystal Checker for Balanced Mixers" I gave data on the excess noise of typical klystrons. Since that paper was prepared, further data has been obtained that permits an expansion of Fig. 6. View full abstract»

    In the maintenance of ultra-high frequency equipments utilizing waveguide, one of the more difficult troubles to diagnose and correct is that of the high standing wave ratio. The question always arises as to whether the antenna or the waveguide is at fault. Sometimes a visual inspection of the transmission system will disclose the difficulty. Too often, however, the physical layout of the system m... View full abstract»
