A radio frequency integrated circuit (635) for a wireless device (500) to an antenna (502), wherein the antenna (502) is coupled to the radio frequency circuit (602) via at least one off-chip inductor (611, 613) that forms a first portion of an antenna matching circuit (530), wherein the integrated circuit (635) includes: a first port coupleable to the radio frequency integrated circuit (635); a second port coupleable to the antenna (502), and a second portion of the antenna matching circuit (530) located between the first port and second port and coupled in parallel with the at least one off-chip inductor (611, 613). The second portion of the antenna matching circuit (530) includes: at least one on-chip inductor (615, 617); and at least one radio frequency switch (606, 616) coupled in series with the at least one on-chip inductor (615, 617) and arranged to selectively introduce the at least one on-chip inductor (615, 617) into the antenna matching circuit (530). |
