BNC connectors use a quick bayonet coupling mechanism and are common in test equipment, video systems, instrumentation, and lower-to-mid-frequency RF links.
| Parameter | Reference | Typical Applications |
|---|---|---|
| Impedance | 50 Ω or 75 Ω | Oscilloscopes, CCTV/video, laboratory instruments |
| Maximum operating range | Typically up to 4 GHz; precision variants may be higher | Select the exact manufacturer part for the required band. |
RF design note: Frequency ratings are model dependent. Connector performance also depends on cable type, mating quality, VSWR, power level, environment, and the complete transmission-line assembly. Do not mix 50 Ω and 75 Ω components without checking system requirements.
SMA is a compact threaded connector designed for microwave applications. It is widely used where small size, controlled impedance, and good high-frequency performance are required.
| Parameter | Reference | Typical Applications |
|---|---|---|
| Impedance | 50 Ω standard | Wi-Fi, GPS, cellular, test fixtures, microwave modules |
| Maximum operating range | Typically up to 18 GHz; high-grade versions may reach 26.5 GHz or more | Select the exact manufacturer part for the required band. |
RF design note: Frequency ratings are model dependent. Connector performance also depends on cable type, mating quality, VSWR, power level, environment, and the complete transmission-line assembly. Do not mix 50 Ω and 75 Ω components without checking system requirements.
N-Type connectors provide robust mechanical construction and good environmental sealing. They are frequently used for antennas, base stations, wireless infrastructure, and coaxial transmission lines.
| Parameter | Reference | Typical Applications |
|---|---|---|
| Impedance | 50 Ω or 75 Ω | Outdoor antennas, RF infrastructure, broadcast systems |
| Maximum operating range | Typically up to 11 GHz; precision variants may be higher | Select the exact manufacturer part for the required band. |
RF design note: Frequency ratings are model dependent. Connector performance also depends on cable type, mating quality, VSWR, power level, environment, and the complete transmission-line assembly. Do not mix 50 Ω and 75 Ω components without checking system requirements.
TNC connectors are threaded versions of the BNC family, providing improved vibration resistance and more stable performance in mobile or outdoor RF applications.
| Parameter | Reference | Typical Applications |
|---|---|---|
| Impedance | 50 Ω or 75 Ω | Mobile communications, GPS, antennas, aerospace equipment |
| Maximum operating range | Typically up to 11 GHz; model dependent | Select the exact manufacturer part for the required band. |
