The project deals with the development of a complete series of radio relay links operating in the 4.4 to 5.0 GHz, 38 GHz and 75/85 GHz frequency bands. In the prototypes of radio relay links operating at 4.4 to 5.0 GHz and at 38 GHz, novel technologies increasing the capacity and the optimality of operation will be implemented. The implemented technologies comprise an automatic selection of modulation, bandwidth switching, suppression of interference caused by crosscorrelation, and beam-width switching of antennas. Research into and development of microwave links operating at 75/85 GHz should result in a new series of circuits of the microwave link in order to define its new architecture considering results of simulations and measurements on an experimental link.
