01. Can you spot the differences between a practical and an ideal microwave mixer?

Long live the instrument 2.0!

  • Instrumentation improved a lot over the last 30 years without challenging the fundamental law governing a measurement system: be the best at 1 measurement under 1 set of operation conditions. In the meantime, the systems-under-test have experienced a major restyling: systems-on-a-chip increased the integration level and the flexibility, at the cost of a very large space fo settings.
  • That is why we need instrument 2.0. This instrument measures all the figures-of-merit of the complete system in 1 single experiment, with a level of accuracy that is tailored to the application. 
  • This topic contributes to the instrument 2.0. It brings instrumentation closer to the flexible, fast and adaptive tool that will be needed to tackle the characterization challenges posed by new applications such as self-driving cars or post 5G telecommunication.

Mixers are key components when it comes to wireless communication systems, and yet their behavior is often idealized in application development and characterization. In this thesis, you will go beyond the state-of-the art and determine how close the real mixed is to his idealized counterpart. Your characterization will change the way mixers are measured, characterized and modeled and is applicable to all the modern and future communication systems. If your curiosity is triggered, we are eager to give you more detailed information (virtually or face-to-face) without any obligation.
