Claim 1:
2. 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 the band selection filter is one of two or more band selection filters, each band selection filter disposed in a respective one among two or more receiver paths, and wherein the controller is configured to tune each band selection filter to a respective one among two or more frequency bands for simultaneous reception of radio signals in each of the two or more frequency bands.
