Its core function is to directionally extract partial electromagnetic energy from the main waveguide to the auxiliary waveguide, while ensuring negligible energy leakage at the isolated port.
Equipped with 1 input port, 2 through port, 3 coupled port and 4 isolated port, as well as standard waveguide flanges for high versatility. An external matched load is required for the isolated port. As the most fundamental configuration, it is suitable for general system integration and compatible with most waveguide interconnection requirements.
The isolated port (Port 4) is pre-installed with an integrated waveguide matched load, forming a three-port device including input, through and coupled ports. No external load is required. Featuring compact outline and anti-reflection performance, it is ideal for embedded installation and space-constrained systems, which simplifies overall layout and improves assembly efficiency.
The coupled port (Port 3) integrates a waveguide-to-coaxial transition adapter (SMA / N type) for direct RF signal output. It enables convenient connection with coaxial systems, widely used on testing instruments to solve interconnection problems between waveguide and coaxial circuits, and meets flexible demands of test and measurement scenarios.
