Claim 3:
4. A multiband radio frequency receiver comprising:
a band selection filter operative to tune a receiver path of the multiband radio frequency receiver to a selected frequency band, the band selection filter comprising a tunable inductor arrangement that is tunable for the selected frequency band and comprises:
a plurality of winding parts arranged in two or more conductive layers of a chip or substrate; and
a switch arrangement configured to control an inductance seen between first and second terminals of the tunable inductor arrangement by selectively connecting the plurality of winding parts in a selected one among two or more inductor configurations; and

a controller configured to control the switch arrangement based on the selected frequency band;
wherein each inductor configuration among the two or more inductor configurations uses at least one winding part among the plurality of winding parts and, for each used winding part that has mutual magnetic interaction with another winding part among the plurality of winding parts, said other winding part is also used in the inductor configuration.
