PROBLEM TO BE SOLVED: To facilitate monitoring in operation by unifying separate modules in an RF block to a single module so as to enhance the space utilization and using a built-in MODEM so as to conduct antenna diagnostic functions or the like. SOLUTION: A forward link section 200 configuring an RF block, 1st and 2nd reverse link sections 300, 400, a triplexer 500, 1st and 2nd directional couplers 600m 700, 1:1 and 2:1 switches, a voltage standing wave ratio sensor 1000, a power supply sensor 1100, a control module 1200 and a main control section 1300 or the like are interconnected to unify the above modules into a single module, and the control module 1200 conducts control/alarm signal processing to diagnose an antenna. |
