摘要： The invention relates to devices comprising field effect transistors to detect the power of an electromagnetic high frequency signal VRF. According to the prior art, the high frequency signal is coupled into the gate G and via a capacitor CGD into the drain D of the field effect transistor FET, the gate G being biased with a direct voltage Vg which corresponds to the threshold value of the FET transistor. The resulting current at the source S contains a direct current portion Ids which is proportional to the square of the amplitude of the high frequency signal. The operating frequency of said power detectors is limited to a few gigahertz (GHz) by the discrete arrangement and especially by the predetermined gate length of the field effect transistor. The aim of the invention is to improve a resistive mixer in such a manner that it can be operated at high gigahertz and terahertz frequencies. For this purpose, the resistive mixer comprises a line which has a first and a second electrical conductor having respective connecting contacts so that an electrical high frequency signal can be coupled into the line, the first conductor having a plurality of series-connected voltage-dependent resistor elements (R) and at least one capacitive element (C) being interposed between the first and the second conductor.

摘要： A monolithic distributed mixer includes a plurality of dual gate field effect transistors (FETs) and first and second corresponding pluralities of T shaped constant K-filters connected respectively to first and second gates of the dual gate FETs for delaying in time the LO and RF voltages applied thereto whereby the phase shift is the same at each filter and the phase difference between the LO and RF at each FET is equal. Thus, the IF energy developed at each drain is in phase. The plurality of dual gate FETs have their drains commonly connected for summing the IF outputs thereof to provide a flat response throughout the bandwidth which is limited only by the cutoff voltages of the FETs or first and second pluralities of K-filters which act as low pass filters.

摘要： A very high frequency harmonic generator utilizes a type III-V (e.g. GaAs) FET. An input signal is applied to the gate of the FET at a sufficient level to induce non-linear functioning of the FET. This causes an output signal to appear between the source and drain having frequency components of at least the tenth harmonic of the input signal. The device is particularly applicable to the generation of microwave signals.

摘要： A miniaturized dual-balanced mixer circuit based on a multilayer double spiral layout architecture is proposed, which is designed for use to provide a frequency mixing function for millimeter wave (MMW) signals, and which features a downsized circuit layout architecture that allows IC implementation to be more miniaturized than the conventional star-type dual-balanced mixer (DBM). The proposed miniaturized dual-balanced mixer circuit is distinguished from the conventional star-type DBM particularly in the use of a 3-dimensional double-spiral circuit layout architecture for the layout of two balun circuit units. This feature allows the required layout area to be only about 15% of that of the conventional star-type DBM.

摘要： A FET comprising two or more gate pads or terminals, and a reflection type oscillator including the above-mentioned FET. In this oscillator, a dielectric resonator is connected through a coupling line to the first gate pad of the FET and an output terminal is connected to the second pad. When the drain pad of the FET is connected to ground, and a suitable value of capacitive reactance is added to the source pad, then a negative resistance -R appears on the first gate pad, and thus oscillation occurs at a resonance frequency fo of the dielectric resonator. If the load resistance value viewed from the second gate pad is set to R, the maximum oscillation output occurs. Accordingly this oscillator enables to set the oscillation conditions between the source and gate pads of the FET, and the output matching conditions between the second gate pad and the output terminal separately, and thus allows to set the oscillation conditions and the output matching conditions, respectively, simultaneously to the optimum values.

摘要： A wide band RF mixer includes a first bifilar balun transformer coupling a high level source of RF signal to the input winding of a trifilar balun transformer. The two output windings of the trifilar balun transformer are connected in series with the drain-source circuits of a pair of GaAs FET transistors. The source of each FET transistor is connected to ground. A local oscillator has a symmetric output signal that is coupled to a self-bias network and also to the gate electrodes of said FETs. An IF output signal is taken between ground and a common junction of the output balun windings. The arrangement provides a high level mixer with good intermodulation characteristics for ultra high frequencies.
