Coaxial Connectors (RF)

Coaxial connectors are an essential electronic component category, which help transmit power and signals between devices. The coaxial connector 142337-75, in particular, is an example of a coaxial connector used in radio frequency (RF) applications. This article provides an overview on the application fields and the working principles of the 142337-75 coaxial connector.

Applications

The 142337-75 coaxial connector is designed for applications in the radio frequency (RF) range, which includes frequencies between 3 kHz and 300 GHz. The connector is used in high-frequency, low-signal transmission of power or signals such as satellite TV connecting, mobile phone signal transmission, and Gigabit Ethernet. Additionally, the 142337-75 is often used for base station antennas, car GPS systems, wireless networks, FTTH lines, and navigation systems.

Design

The 142337-75 connector features a body made from nickel-plated brass, with a gold-plated beryllium copper (BeCu) center contact to ensure superior performance and signal integrity. The insulator is heat resistant and constructed from PTFE Teflon for a low insertion loss and stability. The design also features built-in Water Blocking technology, which protects against moisture, dust, and dirt.

Working Principles

The 142337-75 is designed to transmit signals from low to high frequencies, and performs excellently without introducing any signal distortion. This is because of the inductive properties of its metallic parts and the use of solvent-resistant dielectric insulator.When the connector is attached to an end of a cable or device, the passive electrical properties of the center pin create an inductive connection with the transmitter or receiver. This connection maintains an equal level of current between both the pins, and allows for the transmission of RF signal with very little signal loss. The 142337-75 also features an inner conductor that is open-ended for ventilation, which helps to maintain the signal reproduction. This connector also has a unique ground-shielding layer over the center pin in order to prevent external noise and interference from entering the signal line.

Conclusion

The 142337-75 is a popular coaxial connector designed for applications in the radio frequency range. This connector is often used in satellite TV connecting, mobile phone signal transmission, and Gigabit Ethernet. The connector features a nickel-plated brass body, gold-plated BeCu center contact, and a PTFE Teflon insulator. It is designed to operate without introducing any signal distortion, thanks to its inductive properties and solvent-resistant dielectric insulator.
