Varieties of RF Connectors

 RF or Radio Frequency Connectors are designed to work at frequencies used for signal transmissions for various electronics like radios, antennas and coaxial cables among many others. RF Connectors come in many types. Most common among them are listed below.

1. Type n Connectors

The type N connector handles frequencies up to 11GHz. It is a medium sized connector. The N type connector is a weatherproof connector which is also threaded. This type of connector is used for lower frequency microwave systems where ruggedness is needed and less price of the connector is needed. This connector uses MIL-STD 348.

2. UHF Connectors

The UHF or Ultra High Frequency connector is a RF connector which carries signals at frequencies of up to 100 MHz. They were invented in the 1930s for the radio industry. It is highly used in amateur radios, band radios and marine VHF radio appliances. One thing to note about it is that it is not waterproof and also non-constant surge impedance.

3. TNC Connectors

 TNC connector or Threaded Neill Concelman Connector is a threaded version of a BNC connector. It operates best up to 11GHz frequency spectrum. A TNC connector is widely used in a huge range of radios and wired applications. Its performance is better when compared with a BNC connector at microwave frequencies. It was invented by Paul Neill in the late 1950s.

4. BNC Connectors

A BNC connector stands for Bayonet Neill-Concelman connector. It was commonly used in early computer networks, Now they are used in coaxial cable in radio, television and other appliances and other electronic systems, which use radio frequency and video signals. It has two bayonet lugs on the female part of the connector. They are made for characteristic impedance at either 50 ohms or 75 ohms. They are usually used for frequencies below 4GHz and voltages below 500 volts. 

5. SMA Connectors

A SMA connector or a Subminiature version A Connector were developed in the 1960s as a small and minimal connector. They have a screw type mechanism. They have an impedance of up to 50 ohms and were originally used for 0GHz to 12GHz but the updated modern version is extended to suit up to 18GHz and 26.5GHz. They are compatible with K-connectors which operate up to 40GHz. They are used in microwave systems, hand held radios and mobile telephone antennas. Recently they were also paired with wireless internet antenna systems. They are also a common connector in radio astronomy, especially the ones which work at higher frequencies.

CONCLUSION

RF Connectors are widely used and can be found in almost all kinds of electronic appliances whether big or small. These are really helpful and can improve the quality of the electronic system drastically.
