Abstract
An attenuator having an impedance that is controllable by a first setpoint signal is coupled to a transmission line. A matching circuit having an impedance that is controllable by a second setpoint signal is also coupled to the transmission line. A transformer circuit block also coupled to the transmission line has a complex impedance. A control circuit sets the first and second setpoint signals so as to control a conjugate impedance relationship between the variable impedances presented by the attenuator and matching circuit relative to the complex impedance of the transformer circuit.
