Abstract
An amplifier system is provided for amplifying an input signal to provide an amplified output signal, amplifying an amplified input signal to provide a further amplified output signal, and phase delay compensating variations of the amplifications of the amplified output signal and the further amplified output signal for providing the further amplified output signal with substantially linear amplification under a variable load.
Claims20
An amplifier system comprising:
- amplifying an input signal to provide an amplified output signal;
- amplifying an amplified input signal to provide a further amplified output signal;
- and
- phase delay compensating variations of the amplifications of the further amplified output signal with amplifications of the amplified output signal for providing the further amplified output signal with substantially linear amplification under a variable load.
