Radio Frequency PCB Board Gerber File Cloning has many uncertainties in the current publicly published theory, and is often described as a kind of “black art”. Under normal circumstances, for circuitry layout pattern in the frequency band below microwave (including low-frequency and low-frequency digital circuits), careful planning under the premise of a comprehensive grasp of various printed circuit board schematic reverse engineering principles is a guarantee for a one-time successful design.
For PCB digital circuits with frequencies above microwaves and high frequencies, 2 to 3 versions of the PCB are required to ensure circuit layout drawing quality.
For Radio frequency pcb circuits reverse engineering above microwave frequency bands, more versions of the PCB design and continuous improvement are often required, and it is under the premise of having considerable experience. This shows the difficulty of Radio frequency electronic circuit board design.
