RF/microwave couplers are passive components used in communication systems to split or combine signals from a common transmission line. They are used to distribute power in radio frequency (RF) systems or to measure signals without disrupting the circuit. The primary function of an RF/microwave coupler is to provide a signal that is a precise fraction of the input signal's power level.
There are several types of RF/microwave couplers, including directional couplers, quadrature hybrids, and branchline couplers. Directional couplers are used to split power from a transmission line to a separate output port, while quadrature hybrids are used to combine two signals and achieve a precise phase relationship. Branchline couplers are used to split power between two transmission lines.
RF/microwave couplers can be designed to operate over a wide frequency range, from a few megahertz to several gigahertz. They can also be designed with a variety of coupling ratios, including 3 dB, 6 dB, and 10 dB. RF/microwave couplers are widely used in many applications, including telecommunications, military and aerospace, radar systems, and test and measurement equipment.
