Patent ID: 7368971

Claim:
A high power, high frequency switch comprising: a transmission line including at least three portions that are serially coupled between an input port and an output port to define at least two nodes therebetween, and to carry a high power, high frequency signal between the input port and the output port, the at least two nodes being configured to be biased with a DC bias voltage; a first DC blocking capacitor between the input port and the transmission line and a second DC blocking capacitor between the transmission line and the output port; first and second power transistors including a controlling electrode and controlled electrodes; and at least a third power transistor including a controlling electrode and controlled electrodes, the controlled electrodes of a respective one of the first and second power transistors and of a respective one of the at least a third power transistor being serially coupled between a respective one of the at least two nodes and a reference voltage, the controlling electrodes of the first, second and/or at least a third power transistor being responsive to a switch control signal at a switch control input.
