RF coaxial connectors provide a means of connecting two pieces of radio frequency equipment. Although there are many types of RF connectors available, the RBD-75-S-04 stands out as a reliable and easy to use option for many applications. The following is an overview of the RBD-75-S-04’s application field and working principle.

Application Field

The RBD-75-S-04 is a 75-ohm, SMA-type connector that is primarily used with semi-rigid cables. It is an excellent choice for a variety of applications, including automotive, communication, and military. The RBD-75-S-04 can be used to interconnect radio transmitter/receiver pairs, wireless communication equipment, VHF/UHF radios, and land mobile radios. It is also well suited for the cable-side connection of broadband amplifiers, cellular base stations, and microwave systems.

Working Principle

The RBD-75-S-04 is a high-performance connector that is designed to provide low passive intermodulation (PIM) performance and exceptional electrical performance. It features a quick connect/disconnect coupling mechanism that is easy to use and provides a dependable, gas-tight connection. The connection mechanism itself consists of a threaded coupling nut with two teeth that fit into grooves on the connector body. This ensures that the coupling nut can only be connected and disconnected in one direction, minimizing potential damage to the pins.

The connector also features an inner contact that is gold-plated for maximum conductivity. A secondary contact spring is included to ensure that the contact maintains constant electrical contact, thus ensuring a reliable connection. The contact is surrounded by a rubber gasket that acts as a shock absorber and seals the connector against dust and moisture. The connector body itself is made of machined brass and has a black passivated finish for added durability.

Conclusion

The RBD-75-S-04 is a highly reliable and easy to use coaxial connector that is suitable for a variety of applications. It features a threaded coupling nut and an inner contact that is gold-plated for maximum conductivity and an outer shell that is designed to protect against dust and moisture. The overall design of the connector ensures a dependable, gas-tight connection every time.
