Abstract
This work establishes the closed form equations that can be used to calculate the inter-modulation distortion noise in WCDMA receivers where the distortion mechanisms involve WCDMA modulated blockers. It is shown that the distortion noise depends not only on the power of the blockers but also on the number of channels in the modulated blocker. Simple equations have been provided which can be easily used by circuit designers in each case. The equations have been validated by a direct conversion receiver chip measurements as well as MATLAB simulations.
