In-band intermodulation measurement and simulation of a local multipoint distribution system

Measurement results of the in-band intermodulation performance of a millimeter-wave communication system developed for local multipoint distribution applications are reported. The system employed traveling-wave tubes as the headend power devices for asymmetrical information transfer. Implications of the presented results on system design, and procedures to incorporate the data for system simulation tools to predict the baseband characteristics in terms of representations such as constellation plots are discussed.
