Coaxial connectors (RF) are commonly used for a variety of electronic applications, including RADAR, radio, telemetry and telecommunications systems. The CONREVSMA005-R178 is a specific type of coaxial connector typically used to interconnect two pieces of electronic equipment or to connect to a vehicular-style antenna for two-way radio communications.
The CONREVSMA005-R178 is a type called SMA, which stands for sub-miniature version A. It features a threaded interface that supports a locking nut, which makes it compatible with a variety of accessories for improved stability when connected. The SMA connector has a 50 Ohm female receptacle and a 50 Ohm male plug.
The SMA connector has a unique design that ensures reliable connections between electrical components while keeping insertion loss to a minimum. The connection is achieved by having a defined annular contact area between the two parts of the connector, which are both threaded and form a closed, air-tight cavity. The tightness of the connection helps to maintain a consistent impedance, and therefore reduces interference. The centre contact pin and outer grounding sleeve are both gold-plated, which further helps reduce interference and offers enhanced corrosion resistance.
The connector has a frequency range of dc to 18 GHz. It is designed for use in equipment where electromagnetic interference (EMI) and radio frequency interference (RFI) must be kept to a minimum, such as instrumentation systems, test & measurement systems, RADAR systems, and satellite ground stations. The SMA connector with its threaded interface also has applications in military / aerospace systems and mobile & wireless communications systems.
The working principle of the CONREVSMA005-R178 connector is straightforward but effective. The two parts of the connector are designed to fit together correctly, with the pin of the plug engaging with the female socket of the receptacle and forming a reliable electrical connection. The threaded interface is designed so that when the locking nut is tightened, it creates a pressure that helps ensure the pin is properly seated in the socket and help reduce loose connections that could cause EMI / RFI and crosstalk. The gold-plated centre pin and outer grounding sleeve are designed to conduct ground currents and help protect the connector and signal quality from interference.
In conclusion, the CONREVSMA005-R178 is a high-performance coaxial connector that is designed to provide reliable connections between components in a variety of applications where EMI / RFI must be kept at a minimum. Its 50 Ohm impedance, frequency range of dc to 18 GHz, and gold-plated contacts make it ideal for instrumentation systems, test and measurement, and military / aerospace systems. The unique, threaded interface helps ensure the connection is both secure and reliable.
