Coaxial connectors (RF) are devices used to join coaxial cable, which carries radio frequency signals for audio and video applications. The SF1621-60003 coaxial connector is a 3-pin, sub-miniature connector designed for use in RF applications.

RF connectors operate on the principle of waveguide coupling, which is an electromagnetic wave propagation process. Waveguide coupling works by allowing RF energy to pass through two conductors of different sizes, forming a waveguide to allow propagation of the RF energy. This waveguide couples the energy from the incoming transmission line to the load, creating what is known as the "transmission effect."

The SF1621-60003 connector is designed to reduce insertion loss, which is often seen in standard coaxial connectors, by using higher quality materials and precision machining. The connectors are made from gold plated brass, molybdenum, and aluminum and feature an insulated, spring loaded contact system.

The SF1621-60003 is rated for frequencies up to 6GHz and offers a low return loss of 3dB at 6GHz. The connector can also handle up to 20V AC/DC and has a maximum operating temperature of 125°C. Other features of the connector include a low Self-inductance of 1.2nH/mm, which minimizes signal losses, and a low insertion force of 0.4N.

The SF1621-60003 can be used for a variety of applications including RF test and measurement equipment, wireless communication systems, research and development, and satellite communications systems. The connector can also be used for Digital Audio Broadcasting (DAB) antenna cables and base station feeder cables.

The SF1621-60003 is a reliable and robust connection solution for RF applications and provides a superior connection that is easy to install and maintain. The high quality materials and precision machining ensure the connector remains reliable and effective even under the most demanding conditions.
