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.
Does anyone have any suggestion for a Small Microcontroller Eval board with an inbuilt ADC and have input port to the ADC? If you know it's available from any supplier, please suggest it. Thank you.
ADC preferred spec:
16 bit
the sampling rate of more than 40ksps
Even if your ADC doesn't...
i know the trace needs to be 90ohm up to infinite frequency.
However, it's impossible to design a 90ohm trace up infinite frequency range due to PCB parasitics. how do solve this problem?
i dont think we can practically design 90ohm D+ and D- up to infinite frequency.
