摘要： A digital power amplifier comprising at least two individually activatable amplifiers connected to an output network comprising a first hybrid coupler. An output of a first amplifier is connected to a first input of the first hybrid coupler and an output of a second amplifier is connected to a second input of the first hybrid coupler such that activating an amplifier of the at least two amplifiers causes the amplifier to load modulate another activated amplifier of at least two amplifiers.

摘要： A method of multiplexing control lines of a qubit array includes applying a qubit control signal to a single driveline. The qubit control signal is split on the single driveline between a first resonator and a second resonator. The first driveline is operative to control a first qubit, a second tunable qubit, a third qubit, and a fourth tunable qubit. The first qubit is coupled to the second tunable qubit by the first resonator. The third qubit is coupled to the fourth tunable qubit by the second resonator. A variation in amplitude of the qubit control signal is compensated by adjusting a frequency of the second tunable qubit and a frequency of the fourth tunable qubit.

摘要： Systems and methods for beamforming based on mixing elements together instead of conventional phase shifting are provided. A beamformer can be used to cross-mix the elements with one another to compensate for delays in signal reception. By replacing phase shifters with mixers, the system becomes agnostic to frequency of operation and angle of arrival.

摘要： A power amplifier includes a 3-dB coupler which splits a first signal into a second signal and a third signal lagging behind the second signal by 90°, a carrier amplifier, a peak amplifier, and a hybrid coupler. The carrier amplifier amplifies the second signal and outputs a fourth signal when the first-signal power level is a first level or higher. The peak amplifier amplifies the third signal and outputs a fifth signal when the first-signal power level is a second level or higher, which is higher than the first level. The hybrid coupler includes a first transmission line receiving the fourth signal at its first terminal, and a second transmission line receiving the fifth signal at its first terminal and being open at its second terminal. The first transmission line outputs, from its second terminal, an amplified first signal obtained by combining the fourth and fifth signals.

摘要： A compact bipolarization is provided power dividers for a radiofrequency power source. The divider according to the invention includes four identical orthomode transducers, eight identical waveguides, each waveguide comprising two bends, four identical T-shaped junctions, four identical twists and two power distributors; the four orthomode transducers being of parallelepipedal shape with a square base, each transducer comprising, on each of two adjacent lateral faces, a waveguide connected to the lower face of the transducer; the four transducers being positioned so as to form a square, each transducer being connected to two junctions that are perpendicular to one another, the set of four junctions forming a Greek cross; each pair of junctions that are situated in one and the same plane being connected, by way of two twists, to the two outputs of a power distributor comprising a single input.
