The choice of cable connector is based on the performance and mechanical requirements of the product, such as impedance matching of the connector, VSWR, highest frequency, transmission power matching, etc. This article introduces several common application scenarios of cable connectors.
1. Application of cable connector in wireless base station equipment
Wireless base stations need to transmit high-power radio frequency signals, high-speed digital signals, and similar signals. The input/output ports of the chassis of wireless base station equipment generally use N-type and 7/16-type connectors. Embedded RF modules require blind matching series such as BMA series, DIN series embedded modules (MARCONI) and panel connectors, input/output modules Application of MCX, surface mount series, panel and cable connectors. Finally, semi-rigid cable assemblies and flexible cable assemblies are used to complete the signal connection of each part of the entire device.
2. Application of cable connectors in transmission equipment and switching equipment
In today's large-capacity transmission equipment market, such as voice transmission, data transmission, and image transmission, wiring equipment is used between transmission equipment and switching equipment. This requires the DDF series connector. Digital distribution frame DDF (Digital Distribution Frames): With the development of communication technology, a large number of high-capacity SDH, ATM and other equipment are used, which requires the corresponding development of the RF coaxial connector of its basic components, and it should be smaller in size. The frequency band is wider, the performance is better, and the connection is more reliable.
3. The application of cable connectors on backplanes, network cards and set-top boxes
In recent years, the coaxial connector market has developed rapidly, and BNC type connectors account for a large number of applications in coaxial export Ethernet applications that provide high-speed channels. In the lower layer of the communication link, BNC series connectors are widely used. The BNC series has the characteristics of convenient insertion and removal because of its unique bayonet locking method, which makes it widely used. Recently, because the SMB series connector can improve the density of connector installation, and because of its excellent performance, it can be used for both general commercial applications and military use, so some users gradually choose to apply the SMB series. In fact, there are multiple solutions for the same application, and users can choose their own suitable connector according to their needs.
