A novel tunable inductor with an extremely high Q is described. The inductor consists of coupled RF and drive coils, which employs phase shifting of the mutual components and demonstrates measured results of over 100% inductance tuning and a significant decrease in resistive losses resulting in a measured Q of about 2000.
