RF Connectors: Applications and Types

With advancements in technology come increased expectations for the speed and accuracy of the information we receive. Specifically, equipment that is connected to the radio spectrum is often intended for high-speed data collection, as it is common in industries that rely on efficient communication. As such, Radio Frequency (RF) connectors are designed to complement the highly efficient nature of radio communication, whether this takes the form of radio, television, Wi-Fi, antennae, telecommunication, or high-data-rate wireless transceivers. Regardless of how the user is utilizing the radio waves they receive, we all want our information as quickly as possible, and RF connectors are designed with this in mind. For your better understanding of the different types of RF connectors available and their different applications, this blog will provide a brief overview of this vital part of radio communication.

In industries such as transportation, data communications, and aerospace applications, RF connectors work to provide the user with information as efficiently as possible. As the latest technology incorporates 5G connections, many systems must upgrade to adapt to higher speeds, and both connectors and cables must be correct to the Ghz and Ohm requirements of the system. While RF communication dates back to 1901, technology develops at a rapid pace as we develop more efficient ways to communicate with each other across long distances.

One of the main benefits of radio frequencies is that they travel through the atmosphere with relatively little loss. While radio waves are intangible, RF connectors are designed to transfer information to radio system equipment in a tangible manner through shielded coaxial cables. This allows for the safe transfer of information from an antenna to your radio, enclosure, or surge protector without the worry of interference. While these cables are used in many at-home applications, they are also vital components of mission-critical applications, like aerospace, military and defense, and satellites. These applications require that satellites not only identify and track the location of their planes, but also that the operators can maintain an open channel of communication to the radio tower.

With various applications for radio communication, it is important to choose the best RF connector for your situation. As such, one should consider details like the mechanical dimensions, frequency range, impedance, and coupling mechanism (bayonet or threaded) of the connector prior to purchase. Of the most common types of connectors, most have threaded coupling mechanisms; however, the BNC connector is engineered with a bayonet coupling mechanism and works well for radios, televisions, test instruments, and video signal applications. On the other hand, its frequency is fairly low with a limit of 4GHz with an impedance of 50? and 75?. For low-frequency applications, one may also rely on UHF connectors which have a limit of 1 GHZ and non-constant impedance.

On the other hand, one should rely on SMA connectors for high-frequency, low-power applications, as they have a limit of 18 GHz. For applications in the middle, one should rely on either Type N connectors or TNC connectors, both of which offer a limit of 11 GHz and an impedance of 50?.
