TNC connector is very similar to the BNC connector, and both of them are widely used in RF connectors (RF connector types and frequency range) . Actually, they are two different connectors. Can you accurately distinguish between BNC and TNC? Let us learn together.
The BNC connector was invented in the 1940’s, It ‘s a snap-on connector and it can easily connect and disconnect. It has two bayonet lugs on the female connector, and you can judge if it is connected well. The impedance of BNC Connector is designed to be 50 ohms or 75 ohms , and working frequency from DC – 11 GHz.
TNC connector was invented in the 1950’s, it is a threaded version of BNC connector, whose full name is Threaded Neill-Concelman as we konw. It was originally invented to solve the problem that the BNC connector made noise at microwave frequencies. It has a better performance than BNC connector at microwave frequencies, and TNC connector can be operated in more applications, with the working frequency from DC – 11 GHz.
The main difference between TNC connector and the BNC connector :
First, the BNC connector connected by bayonet , while the TNC connector connected by threaded , and the threaded connection is usually robust than the bayonet connection, so the TNC connector can Work at a higher frequency field.
Second, because of the different working frequencies, BNC connector and TNC connector can use in different application fields.
The application of BNC:
Broadcast (75 Ω)
The application of TNC:
Here is a picture to help you distinguish between BNC and TNC from outline
So through the article, we hope you can get a deeper understanding of the difference betweeen BNC and TNC, more questions you can leave us a message.
