Patent ID: 8150356

Claim:
A polynomial nonlinear term generator comprising: an input RF terminal configured to receive an RF signal; an analog cubic term generator electrically coupled to said RF input terminal, said analog cubic term generator configured to receive said RF signal from said RF terminal and to generate an analog cubic term signal derived from said RF an analog square term generator electrically coupled to said RF input terminal, said analog square term generator configured to receive said RF signal from said RF terminal and to generate an analog square term signal derived from said RF signal; a cubic term mixer assembly electrically coupled to said analog cubic term generator, said cubic term mixer configured to mix a local oscillator (LO) signal with said cubic term signal to generate a synthetic IM3 signal; and at least one multiplier having a first multiplier input terminal, a second multiplier input terminal, and a multiplier output terminal, said first multiplier input terminal configured to receive a selected one of said analog square term signal and said synthetic IM3 signal, said second multiplier input terminal configured to receive said square term signal, said multiplier configured to provide as output an IMn product, where n is greater than 3.
