Patent ID: 8390386

Claim:
A variable inductor, comprising: a first inductor comprising two ends connected to a first terminal and a second terminal; a second inductor comprising two ends connected to said first terminal and said second terminal; a first node provided on said first inductor; a second node provided on said second inductor; and a switch element that switches between a conductive state and a non-conductive state between said first node and said second node, said switch element performing specific switching to provide different lengths of inductor coils, wherein said first node is provided on said first inductor at a first connection part between a first part of a first line of inductors and a second part of the first line of inductors, the first inductor comprising the first line of inductors connected in series, and wherein said second node is provided on said second inductor at a second connection part between a first part of a second line of inductors and a second part of the second line of inductors, the second inductor comprising the second line of inductors connected in series.
