Description of Microwave system
Microwave system is a high-performance, low-cost, secure and reliable transmission products.
Microwave system includes Indoor unit (IDU), Outdoor unit (ODU, the RF unit), antenna and all basic accessories.
Microwave system supply point-to-point radio connection in the telecommunications network, which is widely used in enterprise access, interconnect base stations, emergency communications, community access and relay connecting link.
Microwave system (IDU) is designed for different RF Unit working in different RF frequency band,5.8/7/8/13/15/18/23 GHz. And the IDU used the same IF interface to connect to all these ODUs through coaxial cable.
