RADIO FREQUENCY COMMUNICATION

摘要

A point-to-point radio frequency, RF, communication system (1); e.g. for outside broadcast, comprising: one or more communication units (6) coupled to respective television cameras(4) and displays(5); and a further communication unit (8); wherein the units (6) transmit video data to the further communication unit (8) at frequencies greater than or equal to 50 GHz and at data rates greater than or equal to 1 gigabit/second; and the units (6) receive video data transmitted by the further communication unit (8) at frequencies greater than or equal to 50 GHz and at data rates 250 megabits/second;the units (6) each comprise an antenna (12) used for both receiving and transmitting coupled to an arrangement comprising a waveguide diplexer (34) and an RF transceiver circuit board (32) having sufficient transmit/receive isolation for the transmitting and receiving to take place point-to-point at distances greater than or equal to km. 1
