With the increase of the operating frequency and integration of radio frequency (RF) circuits, the substrate material has an increasingly greater impact on circuit performance. SOI (Silicon-on-Insulat
[size=5]Moderator, where can I buy your board? It seems that there has been no news since the fifth article. I am really interested in your progress! ! ! [/size]

I used a step diode to multiply the frequency 18 times. At the beginning, the output power dropped by 8dB at a low temperature of -10 degrees. The spectrum was normal and recovered immediately after t
The TMS320LF2407 I use needs to be burned frequently. Each chip can only be burned for dozens of times (probably less than 100 times) and then it can no longer be burned successfully.Usually, an error
