【Abstract】This paper briefly explains the working principle of the microwave digital phase shifter and introduces a method of using commercial microwave software to complete the phase shifter design w
When debugging ADS1248, I found that reading and writing registers failed. The ADS1248 data sheet contains too much content. I only read some of the 14 registers in total. It stands to reason that wri
When multiple variables use the same timer (the time the variable changes is an integer multiple of the timer time), how to control the timer to start and stop.I now think of three methods:1. The time
I currently need a frequency multiplier for a project. The required input range is: within a few MHZ-1GHZ. It would be best if the frequency value and the multiplier number can be set. I hope an exper
The circuit principle is as follows: 6N137 isolates a PWM signal, the frequency is 2-10K, and now there is a very annoying "step", about 2 microseconds, the voltage is around 5V. I don't know why this
