Tiivistelmä
The reference radiator has been an indispensable tool for Electromagnetic Compatibility (EMC) laboratories where it is used as a well-calibrated and well-known noise source to ensure the quality of measurement results. The objective of this thesis was to design and implement a reference radiator by using a programmable clock generator Si5351A-B-GT on Microcontroller systems.
The Si5351A clock generator breakout board was used for testing and analysis to build a reference radiator. When being connected to a monopole antenna, the radiator can generate radiated emissions from 12MHz up to 50MHz.
The final device was completed with more features such as measuring temperature based on a sensor and adjusting a frequency being selected by the user through push buttons. The output frequency results are also expected to be more improved. With the criteria of compact and low-cost design, the device is housed into a small metal box. It is very handy for characterizing anechoic chambers or many other things.
