Directional couplers are important components for use in isolating, separating, replicating, and combining microwave signals. They can serve as accurate attenuator measurements as they eliminate reflections. They are incredibly useful in sampling RF signals for use in detectors, gain control and feedback loops. The APTDC-20-00130052-N is part of AmpliTech’s catalog of single and dual directional couplers that offer a wide range of coupling values and frequency ranges. The device comes with N female connectors.
