Block type directional couplers are passive devices mainly used in the field of wireless technology. They couple the defined amount of electromagnetic power in the transmission line to the port, allowing the signal to be used in another circuit.
Dolph Microwave’s DH-900WBDC25PPPPC broadband directional coupler is a wide walled porous energy coupling device operating in the range of 75 to 110 GHz. This coupler provides a nominal coupling level of 25 dB, and the directional coupler is configured to have WR-10 waveguide and UG-387/U compatibility on all ports.
