Generally discussed herein are techniques, software, apparatuses, and systems configured for impedance matching. An impedance matching tuner can include a first tunable capacitor arranged in series with a radio frequency (RF) input, a second tunable capacitor arranged in shunt with the RF input, a third tunable capacitor and a first inductance device arranged in parallel with each other and in shunt with the RF input, and a fourth tunable capacitor and a second inductance device arranged in parallel with each other and in series with the RF input.
