Processing a radio frequency signal

A radio frequency receiver for processing a radio frequency signal, the radio frequency receiver comprising:

• a mixer arranged to:
• receive the radio frequency signal wherein the received radio frequency signal has an interference component;
• and
• down-convert the received radio frequency signal to a lower frequency, wherein the interference component in the down-converted signal is within an interference frequency range;
• an LC based notch filter arranged to:
• receive the down-converted signal from the mixer;
• filter the down-converted signal, wherein the LC based notch filter has a notch centered within said interference frequency range, such that the LC based notch filter is arranged to attenuate the interference component in the down-converted signal;
• and
• output the filtered signal;
• and
• a baseband processing block for processing the filtered signal outputted from the LC based notch filter.

A method of processing a radio frequency signal in a radio frequency receiver, the method comprising:

• receiving the radio frequency signal at a mixer of the radio frequency receiver, wherein the received radio frequency signal has an interference component;
• down-converting the received radio frequency signal to a lower frequency using the mixer, wherein the interference component in the down-converted signal is within an interference frequency range;
• passing the down-converted signal from the mixer to an LC based notch filter of the radio frequency receiver;
• filtering the down-converted signal with the LC based notch filter, wherein the LC based notch filter has a notch centered within said interference frequency range, such that the LC based notch filter attenuates the interference component in the down-converted signal;
• and
• outputting the filtered signal from the LC based notch filter for processing by a baseband processing block.
