Abstract :
In this paper a detector structure for an automatically tuned filter that is well-suited for application at microwave frequencies is proposed. It can be used in a master-slave structure where the response of a master filter at a reference frequency is used to derive a control signal to steer a slave filter in the signal path. The control loop is analyzed theoretically and the result is compared to a measurement.
