Coaxial Connectors (RF): CBBJR79 Application Field and Working Principle

Coaxial connectors are one of the most widely used interconnects with many fields of application, from telecommunications to aerospace. One type of connector is the CBBJR79 series, a coaxial RF connector, also known as a 50 Ohm Subminiature BMA (Board Mounting Application) connector. This connector is a popular choice for applications where small form factor, high-frequency, and a low-profile are necessary.

CBBJR79 has a compact design with 50 Ohm impedance and is available in wide range of connector types such as SMT, Jaw and flip, board mount, and more. The connector is also designed to accommodate varying connector mating heights, and is wide variety of voltage and current ratings. In addition to it, the CBBJR79 also provides superior RF shielding are over conventional connectors offering up to 113 dB average shield effectiveness at 10 GHz. Additionally, non-reflective designs are also available, reducing signal loss.

In terms of its application fields, the CBBJR79 RF connectors are mostly used in super telcom, 5G Mobile, and military fields. Its subminiature design and 50 Ohm impedance make it ideal for many applications. Mobile 5G radio devices such as mobile handsets, routers and telecommunications equipment often need an interconnect that is able to handle the large signals that 5G devices need without suffering from signal loss or degradation and CBBJR79 can easily achieve this. Other applications areas including WiFi devices, instrumentation, VME bus, and more. The CBBJR79 RF connector is also used in military applications, due to its superior shielding and low profile design, which also helps to combat EMI interference.

In terms of how the CBBJR79 works, the connector has an electrical contact interface to connect traces on a printed circuit board (PCB) and a threaded interface for cable connection. This allows for PCBs and cables to be connected with minimal effort. The PCB has a sexless connection and a threaded screw for the cable contact. To make the connection, the threads of the cable contact are inserted into the PCB board and the connection is then secured with an integrated locking ring. The electrical contact interface provides a low-loss point of connection between the board and the cable and the threads enable the cable to be securely fastened. The locking ring provides a secure connection and ensures that the connection is held in place even during transmission of signals.

The CBBJR79 is a popular choice in many different fields due to its high-performance and low profile design. It uses a sexless connection with a threaded screw connector to allow for easy and secure connection between PCBs and cables. It also has a superior RF shielding, low impedance rates, and can operate in a variety of conditions. The CBBJR79 can be used in applications ranging from mobile 5G radio devices to instrumentation and even military fields.
