AD18-31 is a high-performance SMA adapter series with a passivated stainless steel housing.

Because the AD18-31 series is designed with passivated stainless steel, it can provide a longer service life, so it is very suitable for occasions that require frequent connecting and unconnecting.

In addition, the precise design of the connector and the mechanism make the AD18-31 series SMA adapters have excellent return loss and ultra-low loss up to 18 GHz. This makes this series an indispensable laboratory through connector.
