Introduction:The 4246B-20 is a directional coupler from Anritsu Corporation, a Japanese communications and electronics company. A directional coupler is an electrical device that allows relatively low-level signals to be isolated from higher voltage electrical lines. The 4246B-20 is a small, light-weight device and is widely used in laboratory and military applications.Background:Directional Coupling is a technique to extract small signal energy from a single port of two-port transmission line, while having minimal impact on the original signal. By combining a low-loss coupling technique with a high-power, miniature matching network, the 4246B-20 is designed to deliver reliable, high-power signal with minimal distortion to the desired antenna input.Application Field:The 4246B-20 is designed for deployment in a wide variety of applications spanning multiple industries. It is ideal for use in research and development projects as well as in the telecommunications industry and military and defense sectors. With its small size and lightweight design, it can be easily deployed in areas where traditional RF directional couplers are unsuitable.It has high input power handling capacity to extract the signals for applications such as laboratory measurements, RF spectrum analysis, signal processing and satellite communications.Working Principle:The 4246B-20 consists of a pair of input and output couplers, a matching network, and a series of input and output circuits to control the phase and the amount of signal being transferred between the two ports. The input and output couplers are designed to allow for a small amount of the signal to be transferred from one port to the other, while keeping the other signal unchanged.The 4246B-20 operates on the principle of energy conserving coupling, where the power transmitted from one port is equal to the power received from the other port. This ensures that the signal has minimum distortion and minimal effect on the original signal.Conclusion: The 4246B-20 directional coupler from Anritsu is an efficient and reliable device that is ideal for use in applications where traditional RF directional couplers are unsuitable. With its robust energy-conserving design, it ensures minimal distortion and minimal effect on the original signal. This makes it ideal for use in a variety of industries such as the telecommunications industry, military and defense sectors and research and development projects.
