Highlights

Features

  • Measures complex permittivity and loss tangent of thin film, un-clad substrate and low loss sheet materials
  • Complies with IPC test method TM-650 2.5.5.13
  • Works with Keysight resonant cavity software
  • Innovative design is robust and easy to use

Electrical Characteristics

  • TEO11 resonant mode of closed empty cylinders: frequency = 10.03 ± 0.03 GHz
  • TEO11 resonant mode of closed empty cylinders: Q factor = ≥ 20,000 (input coupling at -50dB)

Typical Uncertainty

  • TE011 mode: real part of permittivity: ±1%
  • TE011 mode: loss tangent: ±0.0001
  • Useable higher order TE0np modes: real part of permittivity: ±1 – 2%
  • Useable higher order TE0np modes: loss tangent: ±0.0005

Sample Requirements

  • Non-magnetic (µr* = 1-j0), homogeneous and non-isotropic, with uniform thickness and flat parallel sides
  • Thickness: 0.1mm to 5mm, typically 1mm
  • Minimum length or diameter 56 mm, typically >60 mm
  • Suggested values for 1mm thick sample are: real part of permittivity <100, loss tangent <0.01

The Keysight 85072A 10-GHz split cylinder resonator measures permittivity and loss tangent of thin film, un-clad substrates and low loss sheet materials according to the IPC TM-650 2.5.5.13 test method. Designed for robustness and ease of use, it features precision cylinders to ensure high Q factor and loss tangent resolution. Compatible with the Keysight 85071E-300 materials measurement software, the 85072A and can be purchased separately or as part of a complete turn-key solution.
