This article describes the recent developments in carrier frequency and other frequency generation equipment required for frequency division multiple access systems to transmit from pathways to super-major groups. The authors first discuss the general design principles and then illustrate the different configurations of the small and large offices. Some of the design considerations for the major components of the equipment are given.
