Common Types of RF Connectors
3. From BNC to SMA
Now for the fun part: learning to recognize the most common RF connector types. Let's start with the BNC (Bayonet Neill-Concelman). These guys are easily identified by their bayonet locking mechanism, which allows for quick and easy connections. They're typically used for frequencies up to 4 GHz and are common in test equipment and video applications.
Next up, we have the SMA (SubMiniature version A). These are threaded connectors, known for their compact size and good performance up to around 18 GHz. They're widely used in microwave applications, antennas, and Wi-Fi devices. A smaller cousin, the SMB (SubMiniature version B), looks similar but uses a snap-on connection instead of threads.
Then there's the N connector, a robust threaded connector capable of handling higher power and frequencies up to 11 GHz (and beyond with precision versions). You'll often find these on larger antennas, broadcast equipment, and high-power amplifiers. They're the heavy hitters of the RF connector world.
Don't forget the UHF connector! Despite its name, it's actually best suited for lower frequencies (below 300 MHz). It's a large, threaded connector often used in amateur radio and CB radio applications. And finally, there's the TNC (Threaded Neill-Concelman), a threaded version of the BNC, offering better performance at higher frequencies.
