Coaxial Connectors (RF) - Terminators

Coaxial connectors’ RF terminators are a type of connector that is used to terminate a coax cable. It helps avoid signal loss and impedance mismatching between the connector and the cable, as well as reflecting radio frequency (RF) energy radiated by the cable. They are frequently used in the RF industry due to their very low loss and wide frequency range. Specifically, 7-1393665-2 application field and working principle is used for medium power applications and removes the RF energy that is reflected back from the antenna.

Types of RF Terminators

RF terminators fall under two categories: pulse type and matched load type. The pulse type terminator absorbs energy through a conductor and resistor combination conductive near the antenna, whereas the matched load type terminator reflects energy back down the cable at the same frequency it was sent at. The 7-1393665-2 application field and working principle is of the pulse type, which helps reduce reflected energy from the antenna.

Applications

RF terminators are commonly used in various applications, such as radio broadcasting and radar. It is used to avoid signal loss and impedance mismatching between the connector and the cable when dealing with high-frequency signals. In broadcasting, RF terminators work with transmission lines, while radar uses both transmitters and receivers. In defense applications, it prevents transmitting energy from entering the receiver.

The 7-1393665-2 application field used specifically is for medium power applications. The terminator is used to reduce reflected energy from radiators and filter transmission/reception of unwanted signals with respect to the transmitting or receiving antenna. In this application, the 7-1393665-2 terminator offers low insertion loss & reflects most of the energy sent back to the transmitter.

Working Principle

RF terminators work by absorbing or reflecting RF energy. In the case of 7-1393665-2, Energy is absorbed through a conductor and resistor networks so the impedance matches the same as the antenna impedance. This balances the signal, dissipating the remaining energy in the form of heat. This minimizes the reflection signals of the antenna and minimizes the noise in the receiving area which allows signals to be cleanly transmitted or received without disturbance.

The 7-1393665-2 terminator is designed with copper-clad steel, which makes soldering easy, and the resistor material is Low Temperature Cofired Ceramic (LTCC). The terminator has a 50 Ω impedance and has an operating temperature range of -30 to +85 degrees Celsius. It also provides high-frequency performance up to 6 GHz.

Conclusion

The 7-1393665-2 is a RF terminator used in medium power applications for eliminating reflected signals from the antenna. It is designed to absorb energy through a conductor and resistor combination, minimizing noise and interference. Furthermore, it is designed with copper-clad steel for easy soldering and provides high-frequency performance up to 6 GHz. The 7-1393665-2 is a cost-effective solution for eliminating signal interference, allowing for clean signal transmission and reception.
