Job requirements: • All communication in English • Experience in low noise electronic design and measurements (sub- uV) • Experience with SMD assembly • Measurement equipment to measure uV spectral noise density from 10 to 10 MHz • Provide your resume] • Provide cost and time estimate for this project Job package: The work package is an optimization of a filter for a DC/DC converter module It is “solder and measurement” - work as optimizing via numerical simulation will not work well. No good simulation models exist for the selected DC/DC converter module. You would need to build the circuit for testing, buy the components, solder components and measure the result for various used components. We need some measurement result for each measured combination of component values.. The DC/DC converter module to be used is the XP-Power JCA1005D03 https://au.mouser.com/datasheet/2/942/SF_JCA10-1508860.pdf The filter topology to be applied is explained in the following publication. It demonstrates it on a different DC/DC converter module that has only one output. (The XP-Power JCA1005D03 has two outputs → +15V, 0. -15V) https://recom-power.com/en/rec-n-very-low-noise-filter-for-isolated-dc!sdc-converters-46.html?0 More details to the project are attached as a PDF document. Kindly read the document before applying. Please feel free to ask any question. With kindest regards, Dr Henner Kampwerth |
