Abstract: Conventional transformers operating at high frequencies have problems such as large leakage inductance, large turn-to-turn capacitance, severe skin effect and proximity effect, and local hot...
I made a board using the stm32f407 chip, and the network solution uses the lan8720A chip. However, I encountered a strange problem: After connecting the board to the power system, turn on the power sw...
When it comes to wireless transmission, the issue that everyone is most concerned about is the transmission distance. If it is an ideal transmission environment, this problem is not difficult to solve...
