XC1900A-10S is a kind of RF Directional Coupler. Directional couplers are designed to couple RF signals from traveling along a transmission line to other transmission paths without disturbing the original signal. It acts as a RF power tap that is greatly used in measuring the RF power level of the transmitted signal, or even to redirect a portion of the signal to other circuits.

Compared to other directional couplers, XC1900A-10S has an extra advantage. This RF coupler uses two identical pick-up loops which are not capacitively coupled but mounted opposite each other symmetrically so that the mutual coupling is increased. And the two identical pick-up loops are positioned between two conductive plates that are part of the RF connector housing. The use of these two symmetrically mounted loops results in a power transfer coefficient that can reach 95-100dB between the output and the output port.

In addition, XC1900A-10S has wide applications. The most typical application of the XC1900A-10S is in the cellular telephone industry. It can be used to help the cellular phone base station to detect RF power level of the incoming transmission. And it also can be used to measure the RF signal strength received by the user end. In short, this RF coupler can be used in many situations where precise detection of the RF transmission is required. Moreover, they are often used to provide a signal to counterbalance attenuation of RF signals, or to redirect small portions of incoming signals to other circuits.

XC1900A-10S working principle is based on the principle of electromagnetic induction. The two symmetrically mounted loops in the rectangular housing of the coupler detect the electromagnetic field of the incoming transmission line. As most of the energy is transferred from the input signal to the output port, the loops are able to detect the energy change and transfer some of the energy into a separate output port. This allows the user to measure the amount of energy transferred to the output port without the need for any external measurements.

Finally, XC1900A-10S is a high performance RF Directional Coupler that provides accurate measurements and signal routing capabilities. It is very durable and reliable and can withstand high power levels without any degradation. The wide range of applications makes it an ideal tool for many different industries.
