RF Measurement Technology
Aligment of substrate in the RF measurement facilities
Developing modern, cellular telecommunications products requires high-quality, innovative components and circuits. To ensure they functionality properly, their quality and reliability has to be monitored continuously. The equipment this requires is usually highly specialised and expensive, which particularly applies to the characterisation of components and circuits for the high- and ultra-high-frequency technology. Nevertheless, these devices are imperative for an efficient and successful development of high-quality products.

Measuring technology is used on components, circuits, and systems levels. The demands of each level may differ, but their characteristics are comparable.


Measurement of non-linear parameters till 60 GHz
Typical parameters which are determined using RF measuring technology include:
  • S-parameters
  • noise figures
  • noise parameters
  • phase noise
  • output power of primary and harmonic waves
  • spectrum analyses
  • intermodulations and load-pull measuring


IMST has established a qualified and accredited test centre (DIN EN ISO/IEC 17025, former DIN EN 45001, ISO 9001) for RF measurements. In this test centre, we carry out custom-tailored measuring services. Specialised measurement equipment is available particularly for the non-linear characterisation of components and circuits.

ICs as well as coaxial cables can be measured. Our services range from

  • material characterisations (up to 110 GHz)
  • linear measuring (S-parameters)
  • noise measuring (noise figure, noise parameter, phase noise)
  • non-linear measuring (power measuring, spectra, intermodulation, etc.)up to
  • reliability measuring (temperature change, mechanical stress, humidity, etc.).
