Abstract: We study the third-order intermodulation distortion of a radio frequency receiver in a Beeper with Volterra series analysis. For a cascaded system, we have deve loped a Volterra model for individual circuit of the receiver. We also have studied the relation between the third-order intermodulation distortion of the overall radio frequency receiver and that of the individual circuit. The calculated results are desired for designing the radio frequency receiver, and can be used in other weakly nonlinear distorted receivers.

Key words: Volterra series, radio frequency receiver, the third-order intermodulation distortion
