摘要： A Marchand balun cirucit having a pair of coupled lines of quarter wavelength for dividing and/or combining signals with the same amplitude and opposite phase with each other is improved by inserting a cancellation element between said pair of coupled lines. Said cancellation element may be a transmission line, a capacitor, or an inductor which improves amplitude difference error and phase difference error of a pair of outputs by controlling phase velocity for an even mode so that phase velocity for an even mode becomes equal to that for an odd mode. Thus, a balun circuit with wide operation band, and less error of amplitude difference and phase difference is obtained.

摘要： A new design concept is presented and demonstrated for the fabrication of active and passive components in integrated circuit (IC) devices for microwave signal transmission. High circuit packing density is desirable but the current configurations of the conventional flat strip type conductors present physical limitations to achieving such an objective. The new conductor configuration not only overcomes such circuit packing problems of the conventional line design, but provides additional improvements in performance parameters, such as lower resistance and lower parasitic interactions, an ability to fabricate circuits to design specifications and to improve reliability at low cost. The new concept has been applied to the fabrication of transmission lines, capacitors, inductors, air bridges and to formulating the fabrication steps for a FET. Polyamide film enables an improved fabrication step to be performed in the invention, and a new processing technique for polyimide material has also been demonstrated.

摘要： A variable gain amplifier circuit in which a feedback circuit that feeds back the output signal of an amplifier from its output terminal to its input terminal is composed of an FET. The gate terminal of the feedback FET is connected to the output terminal of the amplifier through a capacitor, and the source terminal of the feedback FET is connected to the input terminal of the amplifier. The gain of the amplifying circuit is controlled by varying the transconductance of the feedback FET by controlling a bias voltage applied to the gate or drain terminal of the feedback FET. This makes it possible to control the gain independently of the physical dimension of the feedback FET, and at the same time, to prevent the input signal from being transmitted from the input side to the output side through the feedback circuit.
