摘要： A digital phase shifter in which a plurality of digital phase shift circuits are connected in cascade. One of the digital phase shift circuits includes at least a signal line, a pair of inner lines provided at both sides of the signal line, a pair of outer lines provided outside of the pair of inner lines, a first ground conductor connected to each first ends of the pair of inner lines and the pair of outer lines, a second ground conductor connected to each second ends of the pair of outer lines, and a pair of electronic switches provided between each of the second ends of the pair of inner lines and the second ground conductor. The pair of outer lines adjacent to each other are separated between the digital phase shift circuits adjacent to each other and the first ground conductor and the second ground conductor adjacent to each other are separated between the digital phase shift circuits adjacent to each other.

摘要： In an embodiment, a method for determining the phase shift between a first signal and a second signal includes: delivering the first signal to a first input of a 90° hybrid coupler; delivering the second signal to a second input of the 90° hybrid coupler; determining a first piece of information relating to a power of a first output signal delivered to a first output of the 90° hybrid coupler; determining a second piece of information relating to a power of a second output signal delivered to a second output of the coupler; and adjusting the phase of the second signal until obtaining a calibrated phase for which the first piece of information is substantially equal to the second piece of information, wherein the first and second signals have identical frequencies, and wherein the phase shift between the first signal and the second signal is equal to the calibrated phase.

摘要： Phase shifters such as networks that can be used in MMIC (Monolithic Microwave Integrated Circuit) and hybrid digital phase shifters, for low loss, wide bandwidth, and high linearity. A digital phase shifter includes input port for receiving signals and output ports for transmitting the signals. Multiple transmission lines are arranged between the input and output ports of the phase shifter. The transmission lines are arranged in a ring with first pair of the transmission lines which are arranged in series in a first path and second pair of the transmission lines arranged in series in a second path. One of the transmission lines of the first and second pairs include quarter-wave hybrid coupled line with coupled-ports and through-ports terminated in short-circuit. Hybrid coupled line can be a Lange coupler with or without RF crossover.

摘要： A phase actuator for a continuously adjustable phase displacement at a first frequency is provided. The phase actuator has a first inductance with tapping point, a first continuously variable capacitor, and a transformation network. A signal input and a signal output of the phase shifter are connected by the first inductance. The first continuously adjustable capacitor is connected in parallel to the first inductance. The tapping point is connected via a transformation network to a reference mass, where an impedance value of the transformation network corresponds to a quarter wave transform of a capacitance value of the first continuously variable capacitance at the first frequency.

摘要： Octagonal phase rotator includes an I-mixer having an I-DAC for steering current between positive and negative phases of an in-phase signal depending on k I-DAC control bits of a control code, a Q-mixer having a Q-DAC for steering current between the positive/negative phases of a quadrature signal depending on k Q-DAC control bits of the code, and an IQ-mixer having n IQ-mixer units each comprising an IQ-DAC for switching a second current unit between the in-phase and quadrature signals, in dependence on a respective bit of n IQ-DAC control bits, and between the positive/negative phases of the in-phase and quadrature signals via I and Q polarity switches respectively of that component. I and Q polarity switches of some different IQ-DAC components switch depending on different I-DAC control bits and Q-DAC control bits respectively. A summation circuit sums weighted output signals from the mixers to produce an output signal of phase.
