Patent ID: 8010075

Claim:
A harmonics generator, comprising: a power detector configured to receive an RF input signal and output a power signal; an envelope detector configured to receive the RF input signal and output an envelope signal; a first high-pass filter configured to receive the envelope signal and output a first signal; a second high-pass filter configured to receive the power signal and output a second signal; a first multiplier configured to multiply the first signal with the second signal and output a first product signal; a second multiplier configured to multiply the second signal with the second signal and output a second product signal; a third high-pass filter configured to receive the first product signal and output a third signal; a fourth high-pass filter configured to receive the second product signal and output a fourth signal; a third multiplier configured to multiply the first signal with the fourth signal and output a third product signal; a fourth multiplier configured to multiply the second signal with the fourth signal and output a fourth product signal; a fifth high-pass filter configured to receive the third product signal and output a fifth signal; and a sixth high-pass filter configured to receive the fourth product signal and output a sixth signal.
