BNC and SMA are the top two positions in coaxial connectors, and the third position needs to be selected between TNC and N-type connectors. In this issue, we will introduce another hot topic, TNC coaxial connector, let's take a look at this coaxial connector that is easy to be confused with BNC, what information we need to know in advance.
TNC connectors act as coaxial connectors and are used to transmit high-frequency signals, usually in the RF range. They are often used in applications where secure and reliable connectivity is critical, such as wireless communication systems, radar systems, and test equipment. TNC connectors are a variant of BNC connectors that are known for their threaded coupling mechanism, which provides a more secure and stable connection.
The most striking feature of TNC connectors is their threaded connection structure. This means that it can be securely screwed onto the mating connector. In contrast to BNC connectors that use bayonet-style connectors, this thread ensures a tight, reliable connection that is not prone to accidental disconnection.
TNC connectors are available in different impedance ratings, the most common being 50 ohms and 75 ohms.
TNC connectors are suitable for a wide range of frequencies, making them suitable for a wide range of applications. Depending on the design and quality of the connectors, the frequency range can be extended from DC (direct current) to several gigahertz.
TNC connectors are known for their durability and ability to withstand harsh environmental conditions. They are commonly used in outdoor applications and are designed to protect against moisture and corrosion.
TNC connectors are available in both male and female versions. The male connector has a male thread, while the female connector has an internal thread. This allows for flexibility when connecting different components of the system.
TNC connectors are available in a variety of sizes, including standard and miniature. The choice of size depends on the specific requirements of the application.
TNC connectors are compatible with a wide range of cable types, including coaxial and semi-rigid cables.
BNC connectors are similar to TNC connectors, but they use bayonet locks instead of threaded connections. This makes BNC connectors faster and easier to connect and disconnect, but less secure and reliable in harsh environments.
SMA connectors are smaller than TNC connectors and can operate at higher frequencies for applications that require high frequencies and compact size.
N-type connectors are larger and more robust than TNC connectors, making them suitable for applications that require high power and low losses.
TNC connectors can work optimally at frequencies up to 11GHz. However, the precise version can handle frequencies up to 18GHz.
TNC connectors have a low loss, typically less than 0.1dB. The exact value depends on the frequency and connector quality.
Like most RF connectors, TNC connectors are designed to maintain a characteristic impedance of 50Ω to prevent signal reflections.
Depending on its manufacture, a portion of the connector can handle peak voltages of up to 500 volts.
