The AR6A Single-Sideband Microwave Radio System: Radio-Line Physical Design

AR6A+ radio is a new high-capacity, long-haul microwave radio relay system operating in the 6-GHz common carrier band. The use of single-sideband modulation for this high-capacity system was made possible only through the achievement of a high degree of system linearity, which was obtained by designing each circuit within the AR6A System to meet a linearity performance objective. Closely coupled with the system and circuits development of AR6A was the physical design of the radio-line equipment.
