I added a power amplifier to the 433M wireless module, and the gain was achieved, but the output frequency increased from 433M to 519M. Is this caused by the self-excitation of the power amplifier? Ho
This paper analyzes the working principle of the lossless MESFET drain injection mixer circuit. In the CAD research of this mixer, the MESFET model expansion technology is proposed. On this basis, the
