Hybrid Coupler Function and construction
1.1 Operation principle and function description
Hybrid Coupler is 3-port microwave waveguide system that splits the input power into two parts,
consequently, allows the simultaneous operation of two outdoor radio units (ODUs). Its application,
together with high performance antennas, leads to use of two independent transmission channels on
a single antenna at the same time.
1.2 Main components of coupler
Coupler is consisted of three parts, waveguide cavity, waveguide absorbing load and flange.
