Abstract
A fast switching device for passing or blocking signals between two input/output ports includes a transistor having a first and a second terminal and a control terminal. The first and second terminals are connected between the two ports. The transistor passes signals between the ports when the transistor is turned on and blocks the passage of signals between the ports when the transistor is turned off. The resistance between the first and second terminals is less than about 10 ohms when the transistor is turned on. The device further includes a driver for controlling the control terminal of the transistor for turning it on or off. Preferably the capacitance between the first or second terminal and a reference potential is less than about 50 pF.
