1. A tunable inductor arrangement arrangeable on a chip or substrate, the tunable inductor arrangement comprising:

  • a tunable inductor comprising;

    a first winding part connected at a first end to a first input of the tunable inductor arrangement;

    a second winding part connected at a first end to a second end of the first winding part;

    a third winding part connected at a first end to a second input of the tunable inductor arrangement;

    a fourth winding part connected at a first end to a second end of the third winding part and at a second end connected towards a second end of the second winding part; and

    a switch arrangement arranged to tune the tunable inductor arrangement by selectively providing at least;

    a circuit comprising the first and third winding parts in series between the first and second inputs; and

    a circuit comprising the first, second, fourth and third winding parts in series between the first and second inputs;

    wherein the first and third winding parts are arranged on the chip or substrate such that magnetic fields of the first and third winding parts are essentially common; and

    the second and fourth winding parts form a pattern on the chip or substrate having a first part directing the magnetic field in a first direction and a second part directing the magnetic field in a second direction, wherein the second direction is opposite to the first direction.
