In addition to our many types of wire connectors, cable connectors, and electrical connectors, 1-Source Components carries a wide variety of RF connectors. Just like regular connectors that connect one device to another, RF connectors (often called coax cable connectors or other variants) are used when it is necessary to transfer radio frequency (RF) from one place to another.
There are many different RF cable connectors used for RF applications, including (but not limited to:
UHF connector: The UHF connector provides a low cost RF coaxial connector suitable for many applications. This type of RF connector has a threaded coupling which prevents it from being removed accidentally. The threading coupling also enables these RF connectors to be tightened enough to enable a good low resistance connection to be made between the two halves. The non-constant impedance of the UHF connector limits its use to frequencies of up to 300 MHz.
N-type connector: A high performance RF connector used in many applications, including broadcast and communications equipment, the N-type connector has a threaded coupling interface to ensure that it mates correctly. These RF connectors are able to withstand relatively high powers when compared to other types of connectors. The standard versions are specified for operation up to 11 GHz, although precision versions are available for operation to 18GHz.
BNC connector: Due to its bayonet fixing that prevents accidental disconnection while still maintaining the ability to easily disconnect when necessary, the BNC connector is widely used when RF connections need to be made. Electrically speaking, BNC RF connectors are designed to present a constant impedance and they are most common in their 50 ohm version (although 75 ohm ones are available).
SMA connector: SMA connectors are sub-miniature RF connectors regularly used for frequencies well into the microwave region. They are often used for providing RF connectivity for microwave components such as attenuators, filters, mixers and oscillators.
SMB connector: Developed to meet the need for RF connectors that were able to rapidly connect and disconnect, SMB connectors do not require nuts to be tightened when two connectors are mated. Instead these RF connectors are brought together and they snap fit together. The SMB RF coaxial connector uses an inner contact and overlapping dielectric insulator structure to ensure a constant impedance and good connectivity.
SMC connector: SMC RF cable connectors provide a beneficial combination of small size and performance. They are optimal for use in environments where vibration is expected.
A number of characteristics should be looked at when considering the best type of RF coaxial connector for your application, including frequency range, physical size, impedance and power handling.
