Patent ID: 6900695

Claim:
A broadband active power circuit comprising: A. at least one circuit input and at least one circuit output, wherein the number of circuit inputs are different from the number of circuit outputs; B. two distributed amplifiers connected to the at least one circuit input and the at least one circuit output, each distributed amplifier being defined by a. plurality of amplifying elements, each amplifying element having an input connection point and an output connection point, b. first artificial transmission lines connected to the input connection points of the amplifying elements, each of the first artificial transmission lines consisting of an inductance located between a pair of input connection points, c. second artificial transmission lines connected to the output connection points of the amplifying elements, each of the second artificial transmission lines consisting of an inductance located between a pair of output connection points, d. a first parallel capacitances across the amplifying elements, between the input connection points and ground, e. second parallel capacitances across the amplifying elements, between the output connection points and ground; and C. a switching element connected between each output connection point and ground and/or between each input connection point and ground, said switching elements operative in two states in response to a control voltage, a first state corresponding to a capacitance and a second state corresponding to a low impedance short circuit.
