High power broadband terahertz source


As the demand for mobile communications increases exponentially, we are approaching the point where existing bandwidth will not be sufficient to meet data transmission requirements.

In our quest for faster and faster communications, we have moved from the radiofrequency spectrum into the microwave spectrum and now to higher frequencies in the THz spectrum.

Fibre cable will be part of the solution but it is too impractical and expensive to be ubiquitous. The backbone network in future telecoms systems will move to high frequency wave wireless connections.

Both satellite and 5G terrestrial communications need a THz frequency solution.


Researchers at the University of Strathclyde have developed a unique, high power, high bandwidth, frequency scalable terahertz amplifier.

The GyroAmplifier will enable high-speed point-to-point wireless communications. The 94 GHz prototype device provides the ability to establish a wireless telecoms network operating at speeds and bandwidths more than 1000x that of existing 4G technologies and significantly greater than those currently planned for 5G.

The frequency band, power and gain of the amplifier has been independently validated by a leading industry measurement provider.

Alongside telecoms, terahertz radiation can improve upon the sensitivity of existing scientific instruments currently using neighbouring regions of the electromagnetic spectrum including spectroscopic imaging and sensing, such as Nuclear Magnetic Resonance (NMR).

Key benefits

  • the GyroAmplifier uses a tuneable source to provide control of the amplitude, frequency & phase, while maintaining high power
  • unrivalled performance at 94 GHz: the GyroAmplifier outputs 5 kW power with 10% bandwidth
  • capable of covering the entire transmit frequency band for communications, amplifying several carriers at the same time & is suitable for a multi-carrier where the frequency routinely changes

Markets & applications

  • the communications market - where tuneable, high power, coherent mm wave is highly desired
  • improved NMR spectroscopy through Dynamic Nuclear Polarisation, enhancing the signal level to produce significantly higher contrast & sensitivity
