FAQ 2014-04-07

Are SMA connectors suitable for low PIM measurements?
Type N and DIN 7/16 are currently the most common interfaces used for low PIM applications. Both are popular for PIM measurements due to their low PIM and higher power handling. However, the SMA connector is also another option for low PIM applications. Keysight’s low PIM RF switches use SMA connectors, which can handle 120 watts of average power at 4.2 GHz for cold switching. The base material for the center connector and housing is BeCu, which is free of ferromagnetic material that ensures low PIM.
