Coaxial Connectors (RF) are connectors used to transmit electromagnetic radiation in the context of broadband application. Being a part of the coaxial line, they are used to join such lines and coaxial cables in order to provide prevention from electrically induced noise and interference. One such type of connector is the 142-4307-406 used in a variety of different applications.

These connectors are part of the miniature coaxial connector series, with their numeric naming indicating their model number. They are primarily used in applications such as cellular communications, satellite communications, WiFi/WiMax, commercial aviation, and automotive applications. These range from providing cellular connection in a car to creating a wireless connection on a commercial plane.

As for the working principle of the 142-4307-406, it contains a threaded coupling nut, an outer shroud, and a two-channel contact. The outer shroud is made of either a die-cast aluminum or a two-piece plastic, with the second part of the plastic having an o-ring for an environmental seal. The contact pin is made out of beryllium copper, which increases endurance and fatigue strength. The threading of the coupling nut ensures a firm connection between the pin and the outer shroud.

The 142-4307-406 can handle transmissions up to 6 GHz, with a very low reflection coefficient at its maximum frequency transfer. These connectors are also compliant with IP67, allowing them to withstand contact with water and dust, making them suitable for uses outdoors. Moreover, the 142-4307-406 has a very wide temperature range, ranging from -55 to +125 Celsius, allowing it to be used in extreme weather conditions.

The performance of the 142-4307-406 is further notable in terms of its VSWR, shielding effectiveness, CTB, and CMA values. VSWR is an abbreviation for a Voltage Standing Wave Ratio, which is a measure of the disturbances in the signal that is conveyed through the connector. The shielding effectiveness measures the degree to which the electromagnetic interference is prevented. Finally, the CTB and CMA values measure the ability of the connector to handle cross-talk and interference.

Overall, the 142-4307-406 is a miniature coaxial connector suitable for various applications, especially those needing a reliable, low-reflection signal. The threaded coupling nut and shielded aluminum fan help reduce radiation and electromagnetic interference, allowing for efficient performance in difficult weather and environmental conditions. It is notable for its high VSWR, shielding effectiveness, CTB, and CMA values, all of which improve performance and signal quality.
