A coaxial line can be matched to a waveguide by means of a probe antenna located ahead of a short-circuiting plunger. An impedance match can usually be achieved by varying any two of the following three dimensions: (a) the off-center position of the

This paper describes a microwave circuit designed for use with the 1553–416A close-spaced triode at 4000 m.c. It presents data on tubes used as amplifiers and modulators and concludes with the results obtained in a multistage amplifier having 90 db

This paper summarizes briefly the chronology of the development of parametric transducers. The early works of Michael Faraday (1831), F. Melde (1859), and Lord Rayleigh (1883) are cited as mechanical examples and the pioneering work of L. Kuhn, J. Ze

It is shown that the backward wave in a directional coupler is related to the shape of the function describing the coupling between tansmission lines by the Fourier transform. This facilitates the design of directional couplers for arbitrary directiv

Results of an ultra-short-wave fading study are here reported. Transmission was carried out in the range of 1.6 to 5.0 meters, over a 70 mile (112.6 kilometer) ocean path, on 106 days during a period of two years. Both horizontal and vertical polariz

Measurements of the microwave noise power available from gaseous discharges, such as in an ordinary fluorescent lamp, show remarkable uniformity and stability. Such tubes are therefore suitable for a new type of standard noise source.

Continuous records of ultra-short-wave transmissionon wavelengths of 2 and 4 meters, over a good "optical" path, have shown variations in the received signal strength. These variations can be explained as being due to wave interference; an interferen

Microwave radio relay repeaters require the use of band-pass filters which match closely the impedances of the interconnecting transmission lines and which suppress adjacent channels adequately. A type of structure culled a Maximally-Flat filter meet
