book is usually slow without practical examples. if you have any practical examples or training slides with practical examples, it will be helpful. eventually i want this for all the RF circuits and not only LNA./
My analog circuit design experience revolves around PCB implementation. I'm learning to implement my analog circuit onto the Integrated Circuit (IC) now. I would like to seek your guidance and help in this. Do you have any training slides or materials that you can share with me on analog circuit...
I want to design a beamformer circuit. There are many beamformer ICs from Analog devices.

I wonder what the circuit looks like. any other materials that will help me to design a beamformer will be greatly appreciated.
I'm looking for compact notes with all the functions and commands in Matlab and their explanation. Where can I find that? If you have it, please share. Thank you so much.
May I ask which type of reflector you use? I'm trying to understand if reflector type has anything to do with 1/16 distance. I have attached popular reflector types here.
Will 1/16 of wavelength spacing work? Do you have any example of a 1/16 wavelength spacing reflector antenna? By the way, I brought the reflector away up to 1/22 of wavelength spacing, and it didn't work.
I'm trying to find the minimum distance a reflector can work. So far, when I put the reflector at a distance very close, it has no effect. At 5mm from the antenna, it's killing the signal at the location of the reflector.
the 1/4 of the wavelength is 90mm. Any idea if this indication at 5mm...
im currently designing/optimizing a reflector for a monopole antenna. When I was optimizing the distance of the reflector, at a particular distance, I could see the far-field radiation got chopped off in the middle (place where the reflector is located) but I could see the radiation at both...
ultimately your PA is a large signal, so large signal parameters such as power and efficiency matter more than S11 so that you can settle for a decent S11 and excellent power and efficiency.
The required ADC sampling rate is 35ksps. we just need a single/couple of ADC. simultaneous sampling ADC is preferred.
I just need ADC + MCU/CPU. I don't need any other DSP functions. I know it can be just an MCU instead of a DSP.
I'm not demodulating audio so Audio DSP/MCU is not required...
I want a simple CPU/MCU with a couple of 16-bit ADC in it. other functions are not required. Any chip available?
if that chip has an eval board which i can test, it will be great.
