En oscillatorbank till en lågfrekvensradar

LORA/VHF

Examensarbete, grundnivå · Linköpings universitet

… operate in the VHF band instead. In order to achieve this, new coherent local oscillators are required. Different options are suggested and one of them is implemented and analyzed.

MEMS baserad referensoscillator

Examensarbete, grundnivå · Linköpings universitet

… with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator …
