BNC – SMA Adapter, 50 Ω, up to 4 GHz

Product detailed description

The BNC to SMA coaxial adapter is used to connect BNC-connector devices, such as oscilloscopes, generators or counters, with cables, antennas and modules with an SMA connector in the DC–4 GHz frequency range. With this adapter, you can connect an SMA cable or LoRa module to an oscilloscope or counter, or conversely, a BNC measurement cable to a NanoVNA or spectrum analyser with SMA. This is a measurement-grade adapter with a max VSWR of 1.15:1 and max insertion loss of 0.20 dB, ensuring that no significant reflections or losses are introduced into the measurement. The centre contact is made of gold-plated beryllium copper and is rated for at least 500 mating cycles.
