記載の高周波スイツチング回路。[Claims for Utility Model Registration] (1) In a multi-input high-frequency circuit, a capacitor, a first diode, and a capacitor are connected in series in the same order between the first input terminal and one terminal of a high-frequency relay switch. The cathode of the first diode is connected to the first input terminal side, and the anode of the first diode is grounded with a resistor and connected to the first power supply line through the resistor. The cathode of the diode is grounded with a resistor and connected to the second power supply line through the resistor, and similarly, a capacitor, a second diode, and a capacitor are connected between the second input terminal and the other terminal of the high frequency relay switch. are connected in series in the same order, and the cathode of the second diode is connected to the second diode in series.
The anode of the second diode is grounded by a resistor and connected to the second power supply line through a resistor, and the cathode of the second diode is grounded by a resistor. connected to the first power supply line through a resistor,
Further, one terminal of the coil of the high frequency relay is grounded, and the other terminal of the coil is connected to the first power line, so that voltage is alternately applied to the first power line and the second power line. A high frequency switching circuit selectively outputs either the signal at the first input terminal or the signal at the second input terminal from a common terminal of the high frequency relay switch by applying a signal to the high frequency relay switch. (2) By making the resistance between the anode of the first diode and the first power supply line a variable resistance, and by making the resistance between the anode of the second diode and the second power supply line a variable resistance, the first Claim (1) wherein the electric fields of the input terminal and the second input terminal are controlled.
High frequency switching circuit as described.
