    The joint IRE-AIEE Task Group 28.4.7, on Transistor Internal Parameters, was organized with the following objectives: 1) To formulate a small-signal equivalent-circuit representation of a transistor, the parameters of which emphasize separately the principal physical mechanisms of the device. 2) To recommend symbols for these parameters consistent with accepted usage and other standards. 3) To exh...

  • A Noise Investigation of Tunnel-Diode Microwave Amplifiers

    Publication Year: 1961, Page(s):739 - 743

    An analysis and derivation of the noise figure of a tunnel-diode microwave amplifier are presented. The agreement between the measured noise figure and the theoretical results is an indirect check on the existence of full shot noise in germanium tunnel diodes at microwave frequencies. The limiting noise temperature of the amplifier is eI0R/2k, and can be approached by using diodes with small (RC) ... View full abstract»

    Several experimental tunnel-diode RF oscillators which operate at frequencies from 610 to 8350 Mc are described. Power outputs an order of magnitude greater than those previously reported in the literature were obtained: 10 mw at 610 Mc, 2 mw at 1600 Mc, 0.7 mw at 2800 Mc, 0.2 mw at 5500 Mc, and 0.01 mw at 7130 Mc. Problems relating to oscillation frequency, power output, and wave shape are treate... View full abstract»

  • Three-Layer Negative-Resistance and Inductive Semiconductor Diodes

    This paper shows that in transistor-like three-layer structures with the base either open-circuited or directly shorted to the emitter region, negative resistances are observed when any two of several effects listed occur simultaneously. At higher frequencies, an inductance is often associated with the negative resistance. A few typical devices are analyzed illustrating an approach to the design t... View full abstract»

  • A Low-Noise X-Band Radiometer Using Maser

    Publication Year: 1961, Page(s):768 - 778
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4808 KB)

    A low-noise X-band radiometer, using a ruby maser preamplifier in radio astronomy measurements, is discussed. The radiometer uses a reflection-cavity maser with voltage-gain bndwidth products as high as 300 Mc at 4.2°K. Less than 1 per cent short-term gain instability and dependable performance are obtained. A system noise factor (excluding antenna spillover) of 0.6 db 43°K) has been obtained. T... View full abstract»

  • An Analysis of the Magnetic Second-Subharmonic Oscillator

    An analysis is given for the second-subharmonic parametric oscillator with two ferromagnetic cores. "Square-loop" reasoning is employed with extreme idealization of the magnetic core properties; the effects of hysteresis losses and saturated inductance are subsequently considered. The steady-state operation, both with voltage and with current pump drives, is studied to determine the values of the ... View full abstract»

  • Properties of Tropospheric Scattered Fields

    Tropospheric scatter tests were performed in the Southern California region in conjunction with extensive meteorological measurements. The turbulent spectra were found to be, in the region of interest, proportional to k-5/3. In general, the scattered signals were found to agree with the turbulent single scattering model predicted by such a dielectric spectrum. Horizontal beamswinging experiments g... View full abstract»
