Resonance has been a fundamental building block of RF circuits since their inception, allowing energy to be recycled and built up over time. However, the classic linear resonant circuit shown has the drawback that it only operates around one resonance frequency. Moreover, as the efficiency of the resonance increases then the bandwidth around this frequency drops proportionally. In practice bandwidth is required for communication and to tolerate detuning or variation at manufacture. This limits the practical efficiency that is possible.

OnTune^TM technology takes a fundamentally new approach to this established technique and opens up the use of an efficient resonance without the same bandwidth limitation. Two principles are outlined of the Self Adjusting Resonance and Dynamic Bandwidth Control that address detuning/component accuracy and communication bandwidth, respectively. These principles are the basis of our patented technology, which yields a step change in performance in many RF applications.
