High data rate millimeter wave radio

摘要

A high data rate millimeter wave radio adapted to receive an binary input data at an input data rate in excess of 3.5 Gbps and to transmit at a transmit data rate in excess of 3.5 Gbps utilizing encoded three-bit data symbols on a millimeter carrier wave at a millimeter wave nominal carrier frequency, defining a carrier wavelength and period, in excess of 70 GHz with differential phase-shift keying utilizing eight separate phase shifts. Preferred embodiments of the invention can support many of the high data rate standards including the following group of protocols or standards: SONET OC-96 (4.976 Gbps); 4xGig-E (5.00 Gbps); 5xGig-E (6.25 Gbps); OBSAI RP3-01 (6.144 Gbps); 6xGig-E (7.50 Gbps); Fibre Channel 8GFC (8.5 Gbps); SONET OC-192 (9.952 Gbps); Fibre Channel 10GFC Serial (10.52 Gbps) and 10 GigaBit Ethernet.
