Patent ID: 8089328

Claim:
An electronic switching device for high-frequency signals between at least two access points, comprising: two switching diodes, one, called a serial diode, being connected in series between a first and a second of the access points, and the other, called a shunt diode, between the first access point and an earth of the device, means for biasing the diodes making it possible to define an on state of the device obtained when the serial diode and the shunt diode are in an on state, and an off state of the device obtained when the serial diode and the shunt diode are in an off state, the device further comprising a first transmission line placed in series with the shunt diode, between the first access point and the shunt diode, a second transmission line placed in series with the serial diode, between the serial diode and the second access point, a third transmission line placed at the common point of the first transmission line and of the shunt diode, a fourth transmission line placed at the first access point, and a fifth transmission line placed at the second access point.
