Introduction

Coaxial connectors (RF) are essential components in any wireless communication system and have been widely used in both Commercial Broadband and Public Communications systems. Coaxial connectors are used to connect an antenna to a transmitter or receiver in order to facilitate RF transmission between the antenna and the radio device. The main types of coaxial connectors used in applications are RF connectors, CBJR, and their derivatives such as SMA, SMB, and others. Among them, CBJR connectors are especially suitable for high frequency applications with broad bandwidths.

CBJR20 Application Field and Working Principle

The CBJR20 is a miniaturized, high performance RF coaxial connector specifically designed to connect antennas for digital television broadcasting applications. The CBJR20 has an extremely low connector loss of 0.3 dB (min) at a frequency of 60 GHz. This low connector loss makes it an ideal choice for high frequency applications. The CBJR20 connector is designed with smooth contact surfaces and features a small contact diameter that reduces signal degradation and ensures reliable connections. It also has a high temperature resistance that allows it to be used in harsh operating environments.

The CBJR20 connector features a male/female interface between two components. On one side, it has an internal male contact that is seated in the connector body. The other side has an external female contact that is seated in a housing. The internal and external contacts are connected by a series of spring fingers which ensure a reliable connection when the connector is mated. The CBJR20 also features an internal ground which improves shielding performance. This ensures reliable transmission of high frequency signals and prevents RF leakage.

The CBJR20 is designed to operate over a wide range of frequencies from 10 MHz to 60 GHz and is suitable for use in a variety of applications including digital television broadcasting, wireless communication systems, and other applications that require high frequency communications.

Conclusion

The CBJR20 is a high performance RF coaxial connector specifically designed for digital television broadcasting applications. It has a low connector loss and a wide range of operating frequencies up to 60 GHz. The CBJR20 also has a high temperature resistance, making it suitable for use in harsh operating environments. Its small contact diameter and internal ground also ensures reliable connections and improved shielding performance. Overall, the CBJR20 is an ideal choice for high frequency applications.
