High power amplifier imd
WebWhen two tones are applied to an amplifier that is non-linear, the nonlinearity causes them to modulate one another, producing intermodulation distortion (IMD) in the form of frequencies known as intermodulation products. (For the mathematical development of this concept, see Reference 1). WebPower amplifier linearity When two or more signals are input to an amplifier simultaneously, the second, third, and higher-order intermodulation components (IM) are caused by the sum and difference products of each of the fundamental input …
