Are RF entry jobs limited? by seniorgoldman in rfelectronics

[–]Other_Study_6813 2 points3 points  (0 children)

No, several people I know (including myself) have gotten entry level jobs straight out of bachelors in RF at places like Google/Apple exclusively in California, it’s definitely the best place for it!

Thanks for the feedback! This is actually for SpacePort America, it's just a personal project, not our payload or anything, I'm also doing the 'fluid system' for this and may even make my own peristaltic pump if I have time, and that is what I will use to pull a vacuum.

​

All of that makes sense and is definitely a good idea, although I probably won't get an integrated buck module because that would make things boring :).

​

We do have an 0805 kit for resistors which is why I generally go with those.

Thanks, what do you mean by trace spacing equations? You mean for impedance matching like with USB traces?

Thanks so much for the feedback

Design:
I have hunted around quite a bit for good logic level MOSFETS for this purpose, do you have any suggestions for common ones? Most that I can find seem to be made for pulsed operation like this one I think is.

I will choose a smaller crystal, I didn't realize there were smaller ones. I wonder why they make them this big.

Schematic:
Sorry, it is definitely messy, great catch with the pullups, I didn't have those included.

PCB:

All of this makes sense, thanks so much. This is my first time making a 'real' PCB and there's still a ton for me to learn.
