Methodology for RF receiver sensitivity analysis using electromagnetic field map

Accurate modelling of a chip is a very important factor when analysing and predicting radio‐frequency (RF) receiver sensitivity. Chip modelling based on the tangential electromagnetic (EM) field from the near‐field measurement just above the top surface of the chip is introduced, and a methodology u...

Description
Summary:Accurate modelling of a chip is a very important factor when analysing and predicting radio‐frequency (RF) receiver sensitivity. Chip modelling based on the tangential electromagnetic (EM) field from the near‐field measurement just above the top surface of the chip is introduced, and a methodology utilising three‐dimensional (3D) EM simulation, for predicting receiver sensitivity generated by the chip‐noise of a mobile phone, is suggested. It is worth noting here that the calculation of absolute coupling values between a noise source and an antenna is possible by using the real measured data source to obtain reliable results.
