RF Directional Coupler from Johanson Technology Inc. : 3 - Page 1

RF Directional Couplers are passive components that sample a small portion of an RF signal for measurement or monitoring purposes, without significantly disturbing the main signal flow. They are essential in applications like power monitoring, signal routing, and testing in RF systems.

Notable manufacturers of RF directional couplers include Mini-Circuits, Anaren, and Werlatone. These companies offer a wide range of couplers with various coupling values, frequency ranges, and form factors.

When choosing an RF directional coupler, parameters such as coupling factor, directivity, and insertion loss are critical for achieving accurate measurements and maintaining signal integrity.
