Abstract:
A linearization circuit that reduces intermodulation distortion in an amplifier output receives a first signal that includes a first frequency and a second frequency and generates a difference signal having a frequency approximately equal to the difference of the first frequency and the second frequency. The linearization circuit generates an envelope signal based at least in part on a power level of the first signal and adjusts a magnitude of the difference signal based on the envelope signal. When the amplifier receives the first signal at an input terminal and the adjusted signal at a second terminal, intermodulation between the adjusted signal and the first signal cancels at least a portion of the intermodulation products that result from the intermodulation of the first frequency and the second frequency.

Claim (Index 11):
An amplifier linearization circuit assembly comprising:\n a difference frequency circuit configured to receive a first signal including first and second frequencies and to generate a second signal having a frequency approximately equal to a difference of the first and second frequencies, the first signal, when received at an input terminal of an amplifier, generating intermodulation between the first and second frequencies in an output signal of the amplifier; and an envelope adjustor configured to adjust a magnitude of the second signal based at least in part on a tuned slope of a shaping function, the adjusted signal configured to be applied to a second terminal of the amplifier to reduce the intermodulation.
