Tuners

Overview of our tuner solutions:

  • Manual stub tuners (cost-effective manual tuners with 2 or 3 stubs)
  • Manual tuners (precision tuners with manual operation)
  • Automatic tuners (high-precision mechanical tuners for automated measuring stations)
  • Automatic multi-harmonic tuners (for precise automatic tuning of two frequencies)
  • Automatic sliding shorts (for checks against short circuits with variable phasing)
  • Manual pre-matching probe mounts (for manual impedance setting of probes)
  • Active load pull tuners (fully automatic electronic tuners for a high number of tuned frequency carriers and for large high-frequency power requirements)
