TUNABLE INDUCTOR DEVICE, TRANSCEIVER AND METHOD Russian patent published in 2017 - IPC H01L23/522 H01F21/12 H03J5/00 H04B7/00 

FIELD: electricity.

SUBSTANCE: tunable inductor device is proposed, placed on the chip or substrate, the method of using the inductor device, as well as the receiver, transceiver, communication device. The tunable inductor comprises the first winding part connected to the first input at one end, the second winding part connected to the other end of the first winding part at one end, the third winding part connected to the second input of the tunable inductor device at one end, the fourth winding part connected to the other end of the third winding part at one end, and a switching group configured to adjust the tunable inductor device. The tuning is performed by selectively creating any of the circuits comprising the first and third winding parts connected in series between the first and second inputs or the circuit comprising the first, second, fourth and third winding parts connected in series between the first and second inputs. The first and third winding parts are disposed on the chip or substrate so that the magnetic fields of the first and third winding parts are substantially common and the second and fourth winding parts are arranged to suppress the electromagnetic coupling to the first and third winding parts.

EFFECT: improved tuning accuracy.
