The RHT, HPT, and DKT series use Semflex's own 50 ohm microporous cable and connectors designed for low VSWR
and excellent phase stability up to 50GHz. The RHT line features interchangeable connector heads which allow users
to calibrate and then replace any interface to either a different gender or different connector type. Phase stability and
repeatability are critical for calibrating and measuring devices with vector network analyzers and all of Semflex's test cable
assemblies feature excellent phase stability. These cable assemblies are made specifically for the rigorous environments associated with
medium and high volume testing with extra strain relief at the connector to cable junction and a variety of ruggedizing options. All three
series of cable assemblies are stocked in standard lengths for quick delivery.
