Embodiment Construction

[0028] figure 1 A tunable inductor arrangement according to an embodiment is schematically illustrated. As will be demonstrated below, the inductor arrangement is preferably arranged on a chip or a substrate. The tunable inductor device comprises: a first winding part W1 connected at one end to a first input INP of the tunable inductor device; a second winding part W2 connected at one end to the first input INP of the first winding part W1 the other end; a third winding part W3 connected at one end to the second input INN of the tunable inductor arrangement; and a fourth winding part W4 connected at one end to the other end of the third winding part. the switching means are arranged to provide, by selectively providing a circuit comprising parallel first and fourth winding parts W1, W4 and parallel second and third winding parts W2, W3, and then corresponding parallel couplings W1, W4; W2, W3 are coupled in series between the first and second inputs INP, INN, or provide a fi...

Abstract

A tunable inductor arrangement arrangable on a chip or substrate is disclosed. The tunable inductor comprises a first winding part connected at one end to a first input of the tunable inductor arrangement, a second winding part connected at one end to the other end of the first winding part, a third winding part connected at one end to a second input of the tunable inductor arrangement, a fourth winding part connected at one end to the other end of the third winding part, and a switch arrangement arranged to tune the tunable inductor arrangement by selectively provide a circuit either comprising the first and fourth winding parts in parallel and the second and third winding parts in parallel, with the parallel couplings in series between the first and second inputs, or a circuit comprising the first, second, fourth and third winding parts in series between the first and second inputs. A transceiver, communication device, method and computer program are also disclosed.

Description

technical field [0001] The present invention relates generally to a tunable inductor arrangement, a radio frequency transceiver or receiver with a resonator having such an arrangement, a communication device, a method of tuning the arrangement, and A computer program for tuning. Background technique [0002] As more frequency bands will be supported in radio transceivers, these frequency bands may span a wide frequency range, such as from 600MHz to 3800MHz, which can be satisfied by a set of resonators. It is known that tuning an LC (inductor-capacitor) resonator more than one octave is difficult, given that many resonators may be required. This issue is further emphasized in the case of carrier aggregation, where communication is performed simultaneously on several different carriers, which can be dispersed anywhere in a wide frequency range. [0003] LC resonators consume chip space when implemented on-chip and are quite expensive when implemented off-chip. Therefore, t...
