Broadband directional coupler

Utilizing a broadband directional coupler is an excellent approach to improve the efficiency of your communications system. A directional coupler is a device that permits the transmission of a signal in one direction, while a receiver transmits the signal in the other direction. By employing a coupler, you can transmit a signal with a strong signal and minimal signal loss.


Circulators and isolators are useful devices

Isolators and circulators are two of the most significant components utilized in broadband directional couplers. These devices function as a circular traffic circle for RF energy, permitting the signal to go in one direction while attenuating the flow in the other direction. They are utilized in hundreds of megahertz to tens of gigahertz applications.

Isolators are typically two-port devices. The first port serves as an input, while the second serves as an output. The RF signal from port A will be sent to port B, but not port C. The loss is little.

A circulator is a device with three ports that links an antenna to a transmitter. The transmitting port on the circulator can be any port. The third port has a termination resistor attached to it. Fourth port is an internal port.
