A continuum of closed-form solutions for voltage waveforms resulting from a complex load at the fundamental and reactive terminations at certain harmonic frequencies is analytically derived for Inverse Class-F power amplifiers based on a finite number of harmonics. The continuum of solutions shows constant RF output power and efficiency for a range of fundamental reactances and appropriately chosen harmonic reactances. The power utilization factor (PUF) decreases towards the boundaries of the continuum and is highest for the unperturbed Inverse Class-F mode from which the continuum is derived, and which is also a particular case within the solution space. The proposed sets of waveforms are new and potentially useful in the design of broadband, high-efficiency RF power amplifiers.
