There are plenty of RF and microwave connectors in the market and choosing one for a specific project can be quite confusing. The wrong decision can cause a problems in your project, so you need to be as fully informed as possible. If you are wondering about the differences between 50-ohm and 75-ohm connectors, then you’ve come to the right place. We will be discussing the key differences between 50-ohm and 75-ohm connectors. If you want to know more information, make sure to read on below!

What Is The Difference Between 50 Ohm and 75 Ohm Connectors - What Is The Difference Between 50-Ohm and 75-Ohm Connectors?

RF connectors are used to connect with cables for RF equipment like TVs, radios, commercial video devices, and ethernet networks. Connectors vary for its uses; it depends on the number of ohms required for the connection to work properly, without any significant signal loss. Connectors and cables are connected using a simple “snap and lock” mechanism which creates a high-quality connection. There are plenty of connectors available in the market; you must avoid the ones made from cheap materials.

Here at SEI, our connectors are easy to use, low-cost, effective, and made from high-quality materials, assuring you that your product will last for a long time. Coaxial cables vary and they are not created equal so it is a must that you learn of the coaxial cable’s appearance.

During the early 20th century, experimentation done showed results that 30-ohm coaxial cables offer the best power handling capability, however, the 77-ohm coaxial cable is needed for lowest signal loss. To compensate for both, 50-ohm connectors are created, which offers the best combination of high-power handling capabilities as well as low signal loss.

Devices that work as a transceiver or transmitter commonly use 50-ohm connectors. Some of the devices are Wi-Fi, two-way radios such as walkie talkies, Radio/TV transmitters, CB radios, and cellular phone repeaters. 50-ohm connectors work well with old analog video formats, such as old television sets. If you prefer high-quality video output; you must use 75-ohm connectors. 75-ohm connectors can adjust their output depending on the input received. This makes them a flexible and versatile option, as they can be used in different applications and devices.

75-ohm connectors are used if you prefer losing the smallest signal strength during the process, as well as low capacitance. If a device using the coaxial connector is a receiver, the 75-ohm connector is the right choice. Examples of these devices are the following: TV receiver boxes, High Definition TVs, AM/FM radio receivers, and police scanners.

The RG-179 coaxial cable uses the 75-ohm connector because it is required in high-temperature applications. The examples of this are the following: medical equipment in hospitals, video cameras, and audio security systems. It is also used for Blu-Ray discs and home theater system equipment. Cable companies use 75-ohm connectors to distribute clear digital video channels. Internet companies use it as well for broadband internet signals.

If you are using a 75-ohm camera to a monitor, the cable used to connect and its connectors must be 75 ohm as well. Do not mismatch a 50-ohm cable and a 75-ohm connector so you can prevent a standing wave from occurring.

A standing wave occurs when a signal reflection is wasted. When a mismatch between 50 and 75 ohm occurs, at least a 5% signal may be lost. Signal losses can add up and this may result in a degraded signal and it results in distorted signal output.
