What are the different types of RF terminators?
RF terminations are one of the most common RF components used in nearly every application and use case where RF systems are employed. An RF termination is simply a terminating impedance that is designed to match the impedance of the transmission line or waveguide used in the signal chain. For instance, if a 50 Ohm coaxial path is to be properly terminated, say at the reverse port of a...
What is a directional coupler what is a directional coupler used for?
Directional RF Coupler A directional coupler is a type of RF coupler that draws a small amount of energy away from the forward and/or reverse signal paths equally. As such, a RF directional coupler is a 4-port passive component with port 1 being the main input port, port 2 is the main output port, port 3 is the forward coupled, and port 4 is the reverse coupled port. An ideal directional coupler...
