Teledyne Lincoln Microwave designs our own proprietary microwave diodes​, which underpin many of our performance advantages.

Our Semiconductor Technology Centre is located at the School of Physics and Astronomy within the University of Nottingham, UK. Facilities include a 90m² ISO class 6 process cleanroom with ISO class 5 laminar flow.

Analytical capability available to Teledyne Lincoln Microwave includes:

• Optical (AOI) and Scanning Electron Microscopy (SEM),
• Energy Dispersive X-ray (EDX) and Electron Backscatter Diffraction (EBSD) Analysis
• Atomic Absorption Spectroscopy (AAS)
• Micro-sectioning and Surface Profiling
• Metallurgical and Chemical Analysis

• Electrical, Mechanical and Thermal Modelling

The Semiconductor Technology Centre specializes​ in development and manufacture of Gunn Diodes and Schottky Diodes:

• Teledyne Lincoln Microwave Schottky diodes have high switching speeds and high-frequency capabilities, which make them well-equipped for use in radio frequency applications including power detector and mixer circuits. The Gunn diode is a unique component. Even though it is called a diode, it does not contain a positive–negative diode junction.
• The Gunn diode can be termed a diode because it has two electrodes. It depends upon the bulk material properties rather than that of a positive–negative junction. The Gunn diode operation depends on the fact that it has a voltage-controlled negative resistance.
  
  

The end uses of our diodes include: Millimeter-Wave Radar and EMC testing, Vehicle speed measurement and Traffic monitoring, THz imaging and Radio-astronomy.
