2.4mm Type RF Connector FAQ
QWhat is the difference between SMA and K connectors?
QWhat is the difference between SMA and K connectors?
QWhy is there a conversion connector for SMA connectors when it is compatible with SMA connectors?
QWhy is there a conversion connector for SMA connectors when it is compatible with SMA connectors?
SMA, 3.5mm, and 2.92mm are compatible and can be mated. Therefore between series adapters are useful at research facilities, universities, and other sites where severe measurements are required.
QAre there connectors with higher frequency and smaller sizes?
QAre there connectors with higher frequency and smaller sizes?
The SMA connector is designed for 18 GHz, the 3.5 mm connector for 26.5 GHz, and the 2.92 mm K connector for 40GHz.
