ABSTRACT:
One aspect of the present disclosure is a control device responsive to control signals for electrically coupling an input node configured for connection to a low impedance source to an output node configured for connection to a transmission line. The control device includes a first controlled impedance device having a pair of controlled nodes connected between the input node and the output node. The first controlled impedance device has a control node for controlling impedance values between the controlled nodes. Also included is a closed loop control circuit connected to the control node of the first controlled impedance device for varying impedance between the controlled nodes continuously over a range of impedance values based on parameters sensed by a parameter sense device. The closed loop control circuit maintains a constant relationship between an output impedance of the control device and transmission line impedance.
