11 GHz FM Radio Link

The paper describes an FM radio link in the 11 GHz frequency band with a capacity of up to 1800 telephone channels and a transmit power of 20 W. After a general outline of the system, some of the critical microwave components are described. Special care was taken to achieve low loss for the branching networks and negligible thermal noise for the active components. Typical one hop performance of a prototype is discussed.
