Power dividers and couplers differ in their working principles and applications. A power divider is used to divide an input signal into multiple output signals, achieving signal distribution and branching; A coupler is used to couple an input signal to multiple output ports, achieving signal coupling and distribution. When selecting and using power dividers and couplers, it is necessary to choose suitable devices based on specific application requirements and system requirements.

The coupler is mainly responsible for signal supervision in wireless transmission. It can extract low-power signals from the main signal in a coupled manner for real-time monitoring and analysis. This device is widely used in various high-power output devices, such as base station TX ports, to ensure the stability of power output and timely detection of abnormal situations. When evaluating coupler performance, key RF parameters include frequency range, return loss, insertion loss, coupling degree, isolation degree, coupling fluctuation, directionality, and intermodulation.
RF power divider is a device widely used in wireless communication systems, whose main function is to divide an input signal into multiple output signals while preserving the original signal characteristics. For passive power dividers, the internal principle is to use microstrip branch lines to construct a branch network, and to use quarter wavelength microstrip transmission lines for impedance matching, so that the impedance seen from each port is equal to 50 ohms, and then to achieve energy transmission with the highest efficiency while splitting.
