​Design activities encompass active and passive instrumentation for applications such as atmospheric remote sensing and radio astronomy; and range from the design of complete instruments to sub-micron scale Schottky diodes, a key enabling technology of terahertz devices. MMTG experti​se also encompasses the design of transceiver components incorporating MMIC and Schottky technology, quasi-optical components and ​blackbody calibration targets.  

The design team use industry-standard software complimented by custom in-house models to ensure state-of-the-art performance. Software used by MMTG includes:​

  • Ansys HFSS
  • Keysight ADS
  • Ticra GRASP
  • Ticra CHAMP 

Examples of recent design work undertaken by MMTG are shown below.
