• RF Radio Frequency
• An RF connector is generally composed of three components including an outer conductor, an inner conductor and an inner insulator, along with other functional components, but it is ensured that the impedance matching is generally achieved through the coordinated design of these three components including the outer conductor, the inner conductor and the inner insulator.
• the outer conductor is usually manufactured through a machining process. In this case, various structures such as steps, diameter changes, etc. are machined inside the outer conductor to achieve the impedance matching of the whole connector.
