Frequently Asked Questions (FAQ) 

  • Q: What is the difference between a 1.85 mm and a 2.4 mm connector on this High Frequency Test RF Adapter?
  • A: The 1.85 mm connector operates up to 67 GHz, while the 2.4 mm connector operates up to 50 GHz. The 1.85 mm uses a smaller center conductor diameter for extended frequency range. Mechanically, 1.85 mm connectors are compatible with 2.4 mm connectors, but mating dissimilar types may degrade VSWR performance and should be avoided in precision measurement applications.
  • Q: Can the 1.85-JKG be used as a calibration standard for vector network analyzers?
  • A: The 1.85-JKG is a general-purpose precision adapter suitable for test setups, but it is not characterized as a metrology-grade calibration standard. For VNA calibration, we recommend using dedicated calibration kits with known open, short, load, and thru standards. The 1.85-JKG is ideal for non-calibration inline adapter applications in test configurations.
  • Q: What is the recommended torque for mating this 1.85 mm adapter?
  • A: The recommended mating torque for 1.85 mm precision connectors is 8 inch-pounds (approximately 0.9 Nm). Using a calibrated torque wrench is strongly recommended to ensure repeatable RF performance and to prevent connector damage from over-tightening. Always follow the connector care and handling guidelines for precision millimeter-wave connectors.
