WitrynaThe IP3 spec allows us to estimate the size of third order IMD3 products at any RF power level . Because IMD products change 3dB for each 1dB change in the fundamentals, … WitrynaWith a narrow IF filter, one can apply more gain (lower reference level) while measuring the IMD3 tones to significantly improve the noise floor and decrease the inherent distortion. Since the two fundamental tones aren t present at the ADC, gain can be applied without overloading the backend. ... Measuring ACLR Performance in LTE …
