(57) Abstract :
An automatic tune and match device (3) and method comprises a reflected power sensor (32) which detects power reflected from a
load (18 18) and an LC matching circuit in series with the load being programmable to minimize the reflected power. The LC
matching circuit includes an inductor matrix (34) in series with the load (18 18) and a capacitor matrix (36) in parallel with the
inductor matrix. A matrix controller (38) configures at least one of the inductor matrix or capacitor matrix based on the detected
reflected power to minimize the reflected power.
