The BU-P4289 is a type of RF Coaxial adapter, a part of the larger family of RF coaxial connectors and adapters. It is a 4-hole threaded coupling female adapter commonly used in RF applications. Further, BU-P4289 is used in the installation of a number of different RF coaxial devices, such as cable assemblies, cable connectors, antennas, and so forth. BU-P4289 is mainly composed of a brass bottom sleeve, a rubberized plastic air insulator, two metal nuts, and back-up washer. The adapter has an operating frequency range of 25 MHz to 1 GHz.

Applications

The BU-P4289 is mainly used in broadband radio and other related high frequency applications. It can be used in different types of communication networks, such as cellular phone networks, satellite communication, point-to-point data links, and private voice and data networks. Further, the BU-P4289 is designed to provide robust mechanical performance while ensuring good electrical characteristics with optimized performance and high quality.

Working Principle

The BU-P4289 employs a two-piece coupling nut connection that can be tightened with a traditional wrench and provides high pressure electrical contact between the plug and the socket. As part of the RF Coaxial Connectors family, the BU-P4289 has the ability to maintain low VSWR (Voltage Standing Wave Ratio) even when under repeated extreme environmental conditions such as vibration, shock, and temperature fluctuations. When the 2-piece coupling nut is tightened, the adapter is made gas-tight and helps minimize interference and reduce unwanted reflections. The adapter includes three separate parts: a brass bottom sleeve, a rubberized plastic air insulator, and two strong metal nuts. The air insulator eliminates the undesirable leakage of electrical signal by holding dielectric material between the two metal parts. Upon tightening the coupling nuts, the bottom sleeve is evenly compressed by the nuts and a good electrical connection is made.

Conclusion

The BU-P4289 RF Coaxial Adapter has a wide range of uses and applications making it suitable for a variety of situations, including broadband radio, satellite communication, and point-to-point data links. Its two-piece coupling nut connection allows for the threads of each piece to be tightened with a single wrench, providing a strong connection and eliminating any gap or space. The adapter\'s rubberized plastic air insulator ensures low VSWR, even under extreme environmental conditions. The BU-P4289 is an efficient and versatile RF Coaxial Adapter designed to provide the user with high-quality performance.
