​Semiconductors Overview

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.
