Latest Patents
Hatamoto's latest patents include a phase-shifting circuit and a multibit phase shifter. The phase-shifting circuit features a first parallel circuit connected across input and output terminals of a high-frequency signal. This circuit is 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. It produces parallel resonance at a prescribed frequency when the first switching element is in the OFF state. Additionally, the circuit includes a series circuit composed of a second inductor and a third inductor, connected in parallel with the first parallel circuit. A capacitor is also included, with its first terminal connected to a point of connection of the second and third inductors. The second parallel circuit is connected across a second terminal of the capacitor and 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. This innovative design allows for effective phase shifting by switching the operation modes of the elements involved.
