    Abstract: Described are transmission line media and microwave structures for combining a multiplicity of elementary discharge devices (e.g., semiconductor diodes) biased for negative resistance at frequencies in a given band to obtain increased high-frequency power and high-frequency bandwidth of useful operation in that band, of microwave energy propagated in the transmission line media. The basic principle involved is to prevent or suppress oscillations in undesired modes of resonance or propagation induced by the use of one or more diodes, by segregating these undesired modes into frequency bands outside the frequency range to be utilized. Under this principle complex networks containing a large number of resonant loops and having as many resonant or normal modes as there are resonant loops are coupled into a primary transmission line so that the network may oscillate or amplify in the desired mode and each diode contributes an equal share of the total power of the network, but the negative conductance properties of the diodes are substantially ineffective at frequencies other than the desired modes.

    Abstract: In a resonant cavity which has multiple modes of resonance within a desired frequency band, certain undesired modes are selectively detuned out of this frequency band, leaving a single desired mode within this band. This is accomplished by the insertion of elongated conductive members into the cavity, so placed and oriented that they cause strong field distortion and detuning of the undesired modes, but cause little effect on the field pattern of the desired mode with little detuning. In the case of a cylindrical cavity operating in a TE011 mode, coupling can be accomplished through an end wall of the cavity substantially without mode interference effects, permitting more economical methods of construction. The principle has been applied to single cavity and multiple cavity resonators and wave filters.

    Abstract translation: 在具有期望频带内的多种共振模式的谐振腔中,某些不期望的模式被选择性地偏离该频带,从而在该频带内留下单个期望的模式。 这是通过将细长的导电构件插入空腔中实现的,因此放置和取向,使得它们引起强场失真并使不期望的模式失谐,但是对微小失谐的所需模式的场模式几乎没有影响。 在以TE011模式工作的圆柱形腔的情况下,可以通过空腔的端壁实现耦合,基本上没有模式干涉效应,允许更经济的构造方法。 该原理已经应用于单腔和多腔谐振器和滤波器。

    Abstract: This invention relates to microwave networks in which radio frequency energy from a multiplicity of sources may be combined into a single transmission line when these sources are of the same frequency and have the same phase. A significant feature of the invention is that energy will be absorbed when the multiple sources have different frequencies or if they have different phases at the same frequency. A particular application of the network is a power combiner for an oscillator or power amplifier when multiple negative-resistance devices are needed, providing a means for avoiding or suppressing undesired oscillations which may occur at multiple frequencies or in nonsynchronous phase relationships.

    Abstract: SOLID-STATE MICROWAVE DEVICES ARE DISCLOSED WHICH GENERATE AND AMPLIFY MICROWAVE ENERGY AT HIGHER POWER LEVELS THAN ARE ATTAINABLE WITH PRIOR TYPES. IN ONE EMBODIMENT OF THE INVENTION A THIN SEMICONDUCTOR SHEET IS BIASED TO CARRY ELECTRIC CURRENT ALONG THE SURFACE. THE SURFACE IS OVERLAID WITH A THIN DIELECTRIC LAYER WHICH IS FURTHER OVERLAID WITH A MOSAIC PATTERN OF NARROW METALLIC STRIPES. NEGATIVE RESISTANCE EFFECTS, RESULTING IN HIGH FREQUENCY OSCILLATION OR AMPLIFICATION, OCCUR THROUGH INTERACTION OF THE MOVING ELECTRIC CHARGES WITH HIGH FREQUENCY ELECTRIC FIELDS INDUCED BETWEEN THE STRIPES.
