Abstract: The present disclosure describes a semiconductor structure that is resistant to induced eddy currents. The semiconductor device includes a substrate, a device layer having electronic devices on the substrate, and a metallization layer above the device layer. The first metallization layer includes first and second terminal traces, a switch, and capacitors. A first terminal of a capacitor of the capacitors is coupled to the first terminal trace via the switch. A second terminal of the capacitor is coupled to the second terminal trace. The first and second terminal traces are disposed along the same side of the capacitors.

Abstract: A phase shifter circuit may include a multiple phase shifter cells (or cells) to selectively shift a phase of an input signal by a desired phase shift value. For example, each of the phase shifter cells may shift the phase of the input signal by a positive fractional phase shift value or a negative fractional phase shift value. The phase shifter cells may include circuitry to form an inductor-capacitor circuit to provide the negative fractional phase shift value and form a capacitor-inductor circuit to provide the positive fractional phase shift value. The phase shifter cells may receive control signals to form the inductor-capacitor circuit and the capacitor-inductor circuit. An electronic device may include multiple phase shifter circuits to adjust a phase of transmission signals and/or reception signals of phased array antennas.

Abstract: This disclosure is directed to a power combiner/divider with improved operating frequency range (e.g., bandwidth) compared to other power combiners/dividers. The power combiner/divider may include an isolation circuit including a first resonant circuit and a second resonant circuit coupled to terminals (e.g., input terminals, output terminals) of the power combiner/divider. The first resonant circuit may attenuate signals having frequencies in a first frequency range below an attenuation threshold between the terminals of the power combiner/divider. The second resonant circuit may attenuate signals having frequencies in a second frequency range below an attenuation threshold between the terminals of the power combiner/divider. Accordingly, the isolation circuit may improve isolation between multiple terminals of the power combiner/divider at a wider bandwidth compared to other power combiners/dividers based attenuating cross-talk between the terminal at the first frequency range and the second frequency range.
