bi-directional coupler ၏လျှောက်လွှာမှတ်စု

အချိန် - 2022-05-21 hits: 20

A bi-directional coupler is actually a 4-port coupler without the internal termination. In this way, the forward and reflected signals can be sampled simultaneously. Companies like AWG Tech and Narda supplies RF bi-directional coupler worldwide. Bi-directional couplers are typically used in test and measurement applications. There is an example to measure the input power and reflected power of the transmission line by using bi-directional couplers, or by implementing multiple tests with directional couplers. Directional couplers are an important type of signal processing device. Their basic function is to sample RF signals at a predetermined degree of coupling, with high isolation between the signal ports and the sampled ports — which supports analysis, measurement and processing for many applications. Since they are passive devices, they also operate in the reverse direction, with signals injected into the main path according to the devices’ directionality and degree of coupling.
