Abstract
The invention relates to an electronic switching device for high-frequency signals. The invention is of particular use in the connection between a microwave frequency antenna and an electronic circuit. This circuit comprises one or two access points designed to be connected to the antenna forming a third access point. In the case of a switch between one access point and the antenna (called an SPST switch), it comprises two switching diodes, one, called a serial diode, being connected in series between the access points and the other, called a shunt diode, between one of the access points and an earth of the device. According to the invention, a first transmission line is placed in series with the shunt diode, a second transmission line is placed in series with the serial diode, a third transmission line is placed at the common point of the first transmission line and of the shunt diode, a fourth transmission line is placed at the first access point, and a fifth transmission line is placed at the second access point. For a switch with three access points, two other diodes and four other transmission lines are added in a symmetrical manner relative to those already described. It is p…
