ABSTRACT:
An RF power supply serves to supply a regulated power amplified RF drive signal to an RF transmitter. The supply includes an RF oscillator for providing an RF input signal. A DC voltage source provides a DC voltage V. A plurality of power amplifiers are provided with each receiving the input RF signal and each having an input for receiving a DC voltage signal, and each serving to amplify the input RF signal by an amount dependent upon the magnitude of the DC voltage signal supplied to its input and thereby provide an amplified RF signal. The amplified RF signals are combined to provide an RF drive signal. The DC voltage V is directly supplied to the input of at least a first one of the power amplifiers. A regulating means serves to regulate the magnitude of the RF drive signal with the regulating means including circuitry for applying a fractional portion of the DC voltage V to the input of at least a second one of the power amplifiers with the fractional portion varying as a function of any variation in the magnitude of the DC drive signal with respect to a desired magnitude thereof.
