On the N Equal Amplitude Sinusoidal Intermodulation Problem.

Determination of the intermodulation power levels in the case of soft-limiting multiple-access repeaters is often critical to system design. An approximate solution to the biased nu th law problem is derived that simplifies the determination of the critical intermodulation power resulting from N carriers. Experimental measurements of a diode simulator are compared with the corresponding approximate analytical results. Finally, measurements with an amplifier operating in the VHF/UHF spectrum are compared with calculations from a biased nu th law model. (Modified author abstract)
