University of Surrey

is a university in the South of England, close to London. About 16.000 students study a large variety of subjects here. The research within the FutureCom project is performed within the Advanced Technology Institute, in particular with the Nonlinear Microwave Measurements and Modelling Laboratories (n3m-labs).

The n3m-labs are a national resource and were the first of their kind in the world to enable the complete characterisation of microwave and millimetre-wave devices, circuits, sub-systems and systems. These include:

  • On-wafer S-parameter measurement
  • Pulsed-IV
  • On-wafer and fixture-based high-power active/passive load-pull
  • Nonlinear vector network analyser (NVNA) measurements.

Multi-physics characterisation using high-frequency electro-optic field probing and advanced thermal reflectance measurement techniques allow dynamic high-frequency electric fields and temperature gradients to be captured simultaneously during device operation.

Extensive cluster computing resources and software allow n3m-labs to study the details of the coupling between the semiconductor device, temperature, and electric fields that can limit the performance of a high-power microwave transistor.

The labs offer core capability comprising comprehensive nonlinear microwave network analysis and on-wafer probing systems for planar micro- and nano-electronic circuits and components.
