The open-circuit impedance parameter called Z-parameter is used to characterize the electromagnetic coupling relationship among the ports:
In order to increase maximum efficiency up to 88.4 percent, it is necessary to provide a short-circuit termination for all even harmonic voltage and an open-circuit impedance for the third-harmonic current.
To increase maximum drain efficiency up to 88.4 percent, it is necessary to provide a short-circuit termination for all even-harmonic voltages and an open-circuit impedance for third-harmonic currents.
