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: An electronic device includes multiple antennas to transmit one or more signals, and a transceiver electrically coupled to the antennas. A transmitter of the transceiver may include splitter circuitry with reduced circuit area that may receive an input signal and generates multiple signals. Moreover, a receiver of the transceiver may include combiner circuitry with reduced circuit area that may receive multiple input signal and generates one output signal. The splitter and/or combiner may include combined circuitry including one or more inductors and resistors to provide a desired total impedance. Moreover, in different embodiments, the splitter and/or combiner may have different number of input or output ports.

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.

Abstract: An electronic device may include signal transmission circuitry having a signal path and a signal source that transmits a signal on the signal path. First and second signal couplers may be coupled to the signal path. Control circuitry may use the first signal coupler to measure the signal at a first reference plane and may use the second signal coupler to concurrently measure the signal at a second reference plane. The signal measurements may include power wave, forward wave, reverse wave, impedance, and/or delivered power measurements. Terminations in the signal couplers may be adjusted to dynamically shift the reference planes. The first and second signal couplers may be formed from first and third metallization layers on a stacked dielectric substrate, where the signal path is formed from a second metallization layer. Additional signal couplers may be coupled to the signal path for concurrently measuring additional reference planes.
