Abstract
A circuit for providing self-interference cancellation in a radio transceiver, the circuit comprising: a first circuit element provided on a first substrate and comprising one or more inductors; a second circuit element provided on a second substrate and comprising one or more capacitors; at least one switching device provided on the second substrate, the switching device being capable of switching one or more of the inductors and the capacitors into or out of a signal path; and a control unit adapted to control the switching device so as to adapt the response of the signal path to perform self-interference cancellation.
Claims19
A circuit configured to provide self-interference cancellation in a radio transceiver, the circuit comprising:
- a first circuit element provided on a first substrate and comprising one or more inductors;
- a second circuit element provided on a second substrate and comprising one or more capacitors;
- at least one switching device provided on the second substrate, the switching device being capable of switching one or more of the inductors and the capacitors into or out of a signal path;
- and
- a control unit adapted to control the switching device so as to adapt a response of the signal path to perform self-interference cancellation.
A self-interference cancellation unit comprising:
- a first circuit element provided on a first substrate and comprising one or more inductors;
- a second circuit element provided on a second substrate and comprising one or more capacitors;
- at least one switching device provided on the second substrate, the switching device being capable of switching one or more of the inductors and the capacitors into or out of a signal path in response to a control signal received from a control unit so as to adapt the response of the signal path to perform self-interference cancellation.
