Conclusion
Multisine Channel Optimization for RF-to-DC Performance Characterization
• A characterization system to optimize the performance of RD-to-DC converters using Multisines was purposed.
• Using this approach it is possible to study the distance relation between TX and RX antennas and the impact on thedevice performance.
• The Multisines impact (uniform and arbitrary spacing tones configuration) on RF-to-DC converters can be tested inReal Time.
• RF-to-DC converters in 5G creates the need of test and measure these WPT devices, which can be done with thischaracterization system.
