P1dB TMFlex series of test cables are designed for demanding test environments where phase stability under continuous flexure is needed. Typical phase stability for <18GHz assemblies is 2 degrees after more than 50,000 flexure cycles. The TMFlex test cables are constructed using specialized stainless steel connectors designed for high retention and stability for over 5,000 mating cycles. Offering durable booting that extends cable life by reducing stress at the critical cable-connector junction, the TMFlex series have connector options that include SMA, Type N, TNC and BNC. A phase stable cable vs. temperature alternative is available using 195PH coax.
