摘要： A switch branch that improves voltage uniformity across a series stack of an n-number of transistors is disclosed. A first one of the n-number of transistors is coupled to an input terminal, and an nth one of the n-number of transistors is coupled to an output terminal, where n is a positive integer greater than one. Predetermined parasitic capacitances associated with each of the n-number of transistors are adjustable with respect to capacitance value by predetermined amounts by dimensioning and arranging at least one metal layer element in proximity to the series stack of the n-number of transistors. Capacitance values for the predetermined parasitic capacitances are selected such that a voltage across the series stack of the n-number of transistors is uniformly distributed. In this way, the n-number of transistors can be reduced without risking a transistor breakdown within the series stack of the n-number of transistors.

摘要： An RF system for reducing intermodulation (IM) products is disclosed. The RF system includes a first nonlinear element and a second nonlinear element, wherein the second nonlinear element generates inherent IM products and the first nonlinear element is adapted to generate compensating IM products. Alternatively, the first nonlinear element generates inherent IM products and the second nonlinear element is adapted to generate compensating IM products. The amplitudes of the compensating IM products are substantially equal to amplitudes of the inherent IM products. The RF system further includes a phase shifter that is adapted to provide a phase shift that results in around 180° of phase shift between the inherent IM products and the compensating IM products. The phase shifter is coupled between the first nonlinear element and the second nonlinear element.
