I used PIC16F684. I used C before, but found that the FLASH was too small, with a capacity of 2K, and I couldn't handle it with C language. So I used assembly language instead. All the codes were writ
The power amplifier PA in the RF front end of the wireless communication system is a very critical device. Its main function is to amplify low-power signals to obtain a certain amount of RF output pow
As shown in the figure, there are two questions:
1. What kind of feedback is introduced into the circuit shown?
2. The closed loop gain of the circuit. Thanks everyone.
What is the significance of connecting two capacitors in series at the power input? The capacitance of these two capacitors is 102. Can't I use a 104? And the input is only 12V. If it is due to the wi
Because copper is easily oxidized in the air, the copper oxide layer has a great influence on welding, and it is easy to form false welding and virtual welding. In severe cases, it will cause the pad
