1. A radio frequency front end of a receiver comprising:
- a tunable filter for receiving a signal;
a controller for tuning the tunable filter; and
an interference detection circuit comprising;
a power detector for detecting interference exceeding a threshold and causing an interrupt at said controller; and
a frequency detector for detecting a frequency of interference, said frequency detector providing an input to said controller,wherein said controller tunes said tunable filter in response to the interrupt and based on the input from said interference detection circuit.

Abstract
A radio frequency front end of a receiver including a tunable filter receiving a signal; a controller for tuning the tunable filter; and an interference detection circuit configured to detect interference and provide an input to a controller, wherein the controller tunes the tunable filter based on the input from the interference detection circuit. Also a method for removing interference at a radio frequency front end of a receiver, the method detecting interference at an interference detection circuit; and tuning at least one tunable filter to at least one frequency of the detected interference.

13. A method for removing interference at a radio frequency front end of a receiver, the method comprising:
-
detecting interference at an interference detection circuit, the detecting comprising; finding, at a power detector, whether interference power exceeds a threshold; and if interference power exceeds the threshold, determining, at a frequency detector, the frequency of the interference; and tuning at least one tunable filter to the frequency of the detected interference. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
