The functionality verification of a mixed-signal sys- tem on chip requires the model for RF front-end with high simulation efficiency. The pure passband model cannot meet this requirement when a long system time simulation is run. The equivalent baseband model is an alternative. In this work, a new baseband modeling method based on a self-defined signal type is realized on the platform of SystemC/-AMS. This method can more accurately describe the block nonlinearity than the traditional equivalent baseband model. For the application in the design of a global navigation satellite system (GNSS) receiver front-end, the baseband simulation based on this method has much faster simulation speed than passband simulation.
