Coaxial Connectors (RF) - Accessories

The RFI3157-7 is a high performance coaxial connector designed for a wide range of broadcast applications, such as professional television and radio systems. This 7mm diameter connector, developed by radioshack Corporation, has a longer-lasting contact and improved shielding effectiveness.

The RFI3157-7 consists of a standard 7mm pin and socket for attaching molded PC dielectric and an adjustable built-in Ferrite Core that allows it to successfully reduce unwanted high frequency interference. This connector is available in several different versions, including an adapter kit that includes all components necessary to properly install the connector.

Application Field

The RFI3157-7 is specifically designed as a high-performance connector for professional broadcast applications, such as FM, DAB and TV Receivers, Digital Audio Broadcast Systems, Satellite Receivers, and Cable TV Systems. Its adjustable ferrite core provide the additional shielding effect necessary for these environments. Additionally, its lower contact resistance allows higher frequency signals passed through without distortion.

Working Principle

The RFI3157-7 connector utilizes a pin and socket assembly for the body construction. The pin is made of brass and plated with gold to ensure a low-contact resistance that keeps the signal passing without distortion. The socket utilizes a dielectric material to insulate the contact between the pin and the socket itself. The contact between the two components is secured with the use of a crimped sleeve. Furthermore, the connector has an adjustable ferrite core securely placed at the rear of the component. The ferrite core amplifies the signal shielding effect and allows for an effective reduction of high frequency interference.

Once properly installed, the connector provides a reliable connection for the broadcast signal with a low insertion loss and a high dynamic range. This allows for longer cable lengths and increases the overall signal range of the broadcast system.

The RFI3157-7 connector is an essential component for any professional broadcast application. Its adjustable ferrite core and improved shielding effects make it ideal for systems that require a high performance performance connection for broadcast signals.
