摘要： A solid state device chip including diodes (generating a higher frequency output through frequency multiplication of the input frequency) and a novel on-chip power combining design. Together with the on-chip power combining, the chip has increased efficiency because the diodes' anodes, being micro-fabricated simultaneously on the same patch of a GaAs wafer under identical conditions, are very well balanced. The diodes' GaAs heterostructure and the overall chip geometry are designed to be optimized for high power operation. As a result of all these features, the device can generate record-setting power having a signal frequency in the F-band and W-band (30% conversion efficiency).

摘要： The invention can be used for telecommunications, measuring and other devices in order to produce stable superhigh frequency signals. An IMPATT diode (4) operating in the cascade break-down mode and having a sharp nonlinearity transforms an input signal in such a way that ultraharmonics which multiple in respect to the frequency of an input signal ω0 occur in a frequency spectrum. An output stage of a multiplier is used in order to separate an output nω0 frequency and to suppress adjacent frequencies. In order to tune the output stage to the nω0 frequency, a tuning plug (8) and short-circuiting pistons (13) are used. The tuning plug (8) is arranged above an upper electrod of the IMPATT diode (4) (inside the axis of the diode). The tuning plugs (13) make it possible to tune resonance capacitance to the nω0 frequency and remove energy towards the output part of a T-bend in which a wave guide pass-band filter (15) is disposed. Said filter (15) is embodied in the form of sections of a waveguide (14) on whose E-plane a thin metallic diaphragm is arranged, said diaphragm being provided with windows (16) disposed along the axis of the waveguide. The inventive multiplier ensures high converting efficiency.

摘要： A subharmonic image rejection and image enhancement mixer for mixing millimeter wavelength signals using a low conversion loss technique is described. A local oscillator frequency from an external source is fed to a first subharmonic mixer and through a phase shifter to a second subharmonic mixer. The phase shifter delays the local oscillator signal by (90.degree./n), where n is the multiple of the subharmonic mixers and is greater than 1. The first and second subharmonic mixers mix the local oscillator frequency with an input signal, which includes a desired frequency and an image frequency, to produce an intermediate frequency having a desired component and an image component at a select phase. A 0.degree.-90.degree. hybrid separates and terminates the image component of the intermediate frequency. The input port that feeds the input signal to each subharmonic mixer is dimensioned so as to provide a virtual image short termination or an image short termination to a self-generated image signal from each subharmonic mixer, thereby decreasing the conversion loss of the frequency mixer.

摘要： A low phase noise frequency multiplier is disclosed for multiplying a sine wave obtained from a low phase noise crystal oscillator to higher frequencies than can be directly obtained from a crystal oscillator. The multiplication occurs without the ordinary increase in phase noise. The multiplier, when tripling the frequency contains a low phase noise frequency doubler. The double and triple frequency terms in the tripler are synthesized from two orthogonally related derivatives of the same wave, which are then multiplied in a double balanced mixer. The process reinforces the desired harmonics while not reinforcing the short term random phase noise, and produces a substantial improvement in the single sideband phase noise ratio over conventional frequency multipliers.

摘要： A subharmonic mixer is shown to comprise two pairs of matched antiparallel GaAs diodes disposed on a dielectric slab and operative with microstrip circuitry. By suppressing the fundamental mixing products, mixing the radio frequency signal with the second harmonic of a local oscillator (LO) signal and using relative phase differences of the LO signals in the two pairs of diodes, undesirable effects from spurious signals are minimized.

摘要： By inserting a rectangular conductive flat member having uninterrupted straight edges into a waveguide in contact relation of their edge portions to the waveguide walls in parallel with an electric field therein, cut-off frequencies at portions of the waveguide to which the conductive flat member is inserted become higher to form a cut-off region. The conductive flat member is composed of a conductor plate or by evaporating a conductive thick film on a dielectric or magnetic plate. The conductive flat member occasionally lined with a non-conductive flat member is provided with circuit elements such as slots formed by punching and strip lines or semiconductor diodes formed by evaporation, and microwave circuits having various functions such as filter circuits, directional couplers, oscillator circuits, frequency converter circuits, frequency multiplier circuits, switch circuits, phase shifter circuits, etc. are constructed on the conductive flat member by combination of the circuit elements through mutual coupling therebetween. These microwave circuits are coupled to transmission regions of the waveguide adjoining both sides of the cut-off region by circuit elements located at the end portion of the conductive flat member. Accordingly, only by inserting into the waveguide a conductive flat member on which various circuit elements are provided, desired microwave circuits of various kinds are constructed very easily inside the waveguide. Such microwave circuits are small in size and low in transmission loss due to elimination of waveguide converters conventionally used, and are suitable for massproduction due to simplicity of structure and ease of manufacturing and assembling which result from mechanical working technique of high degree being unnecessary.

摘要： A waveguide component for use in microwave range or in quasimillimeter wave range such as, for instance, a frequency multiplier or a frequency down converter. The waveguide component comprises a strip line element functioning as an antenna for resonating at least two electromagnetic waves having different frequencies and a semiconductor element of which one end is connected to the strip line. Both the strip line and the semiconductor element are provided onto a dielectric base plate by means of printing circuit technique. The dielectric base plate is mounted in a waveguide in a manner that the strip line element extends parallel to a high frequency electric field in the waveguide. The waveguide component having above construction is able to be miniaturized by the elimination of the conventional tuning circuit elements and due to its improved semiconductor mounting it is suitable to be used in quasi-millimeter wave range.
