About the 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 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.

Our facilities

Our facilities include:

• Load-pull capability
• Thermal sensing and electromagnetic field sensing (for devices operating in-situ)
• Electronic circuit modelling using large-scale computer clusters.

NPL facilities

Facilities at NPL include:

• Millimetre- and submillimetre-wave frequency range extenders (to 750 GHz)
• PCB probe stations
• On-wafer probe stations (to 220 GHz)
• Modelling capability using electromagnetic time- and frequency-domain field solvers.
