摘要： The invention refers to a circuit and a method for detecting the impedance of a load, whereby the circuit and the method can be used by an impedance matching circuit. Impedance matching circuits need a complex algorithm to adjust the impedance accordingly. This algorithm renders the response time to be long. It has been found out that the complexity partially stems from the fact that the phase of the reflection coefficient is not known over the full range of 0° to 360°. A quadrature phase detector is used to provide the full phase information.

摘要： A phase-shifting circuit includes: a first parallel circuit which is connected across input and output terminals of a high frequency signal, composed of a first inductor and a first switching element that exhibits a through state in an ON state and a capacitive property in an OFF state, and produces parallel resonance at a prescribed frequency when the first switching element is in the OFF state; a series circuit composed of a second inductor and a third inductor and connected in parallel with the first parallel circuit; a capacitor having its first terminal connected to a point of connection of the second and third inductors; and a second parallel circuit which is connected across a second terminal of the capacitor and a ground, composed of a fourth inductor and a second switching element that exhibits a through state in an ON state and a capacitive property in an OFF state, and produces parallel resonance at a prescribed frequency when the second switching element is in the OFF state. The phase-shifting circuit establishes by switching an operation mode of setting the first switching element at the ON state and the second switching element at the OFF state, or an operation mode of setting the first switching element at the OFF state and the second switching element at the ON state.

摘要： A tuning amplifier (1) is provided with two cascade-connected phase-shifting circuits (10C and 30C) and an adding circuit composed of a feedback resistor (70) and input resistor (74). The circuit (10C) is constituted of an operational amplifier (12), a resistor (18) one end of which is connected to the inversion input terminal of the amplifier, a resistor (20) connected between the inversion input terminal and the output terminal of the amplifier (12), a series circuit which comprises a capacitor (14) and a variable resistor (16) and one end of which is connected to the other end of the resistor (18). The fluctuation of the output amplitude of the circuit (10C) is suppressed when the tuning frequency of the circuit (10C) is changed because the resistance values of the resistors (18 and 20) are equal to each other. When the signal inputted to a voltage dividing circuit composed of resistors (21 and 23) is taken out as an output, the amplifier (1) itself has a gain and the amplitude of the signal is amplified simultaneously with the tuning operation. The phase-shifting circuit (30C) has the same structure as that of the circuit (10C), and total phase shift by the circuits (10C and 30C) is 360 DEG at a prescribed frequency. Therefore, the amplifier (1) outputs only a signal having a prescribed frequency as a tuning signal.

摘要： A phase shifting electric circuit (1) comprises units for conveying an input signal (V1) from a main signal input (12) to a main signal output (11). The circuit (1) has a first signal path (18), from the input (12) to the output (11), along which a connectable and disconnectable first active unit (3) is arranged and also a second signal path (19) along which a connectable and disconnectable second active unit (4) and a 180 degree phase shifting unit (2) are arranged. By a method, a selection is made which of the active units (3, 4) is to be in a connected condition after which control signals (U1, U2) to the units (3, 4) sets them in a connected and disconnected condition respectively with the outcome of a transmission from the output (11), depending on the selection, either a non-phase shifted signal (V1') or a 180 degree phase shifted signal (V2'). Depending on the function of the active units, (3, 4) the signal (V1', V2') can also be affected in other respects than its relative phase.

摘要： A phase shifter comprises a coarse phase tuning arrangement and a fine phase tuningarrangement. The coarse phase tuning arrangement provides a discrete number of phase shifts. The fine phase tuning arrangement includes a RLC network, having a resistor, an inductor and a capacitor. The fine phase tuning arrangement also comprisesan optical arrangement for varying the resistance value of the resistor. This phase shifter is able to obtain broadband, continuous 360o phase shifting also a Gigahertzfrequencies. It also allows close to linear phase shift versus frequency resulting in truetime delay capability, very low insertion loss and high value of maximum phase adjust.
