Abstract
A tuning system connected to a tunable RF circuit is described. The tuning system obtains an output of a sensing circuit and processes the output in the control circuit in order to tune one or more passive components in the tunable RF circuit. A related method is also described.
Claims17
A system comprising:
- a sensor circuit configured to provide a first signal to tune one or more adjustable passive elements, the sensor circuit comprising one or more adjustable passive elements;
- a tunable radio frequency circuit configured to receive a second signal, the tunable RF circuit comprising one or more adjustable passive elements, and
- a control circuit operatively connected to the sensor circuit and the tunable RF circuit whereby the control circuit receives the first signal from the sensor circuit and provides the second signal to the tunable RF circuit to configure the one or more adjustable passive elements of the tunable RF circuit.
A method of tuning a radio frequency circuit comprising:
- providing a sensor circuit comprising one or more adjustable passive elements, the sensor circuit measures one or more values associated with the one or more adjustable passive elements corresponding to a first signal;
- providing a tunable RF circuit comprising one or more adjustable passive elements, wherein each adjustable passive element of the tunable RF circuit corresponding to a respective passive element of the sensor circuit;
- and
- providing a control circuit configured to track and adjust the tunable RF circuit based on the first signal.
