Hi all, I've had some experience putting together a prefab circuit board, like real simple stuff and aiding friends or classmates soldering. However, I am here today because I was picked for a fellowship over summer to get more hands on learning at my university.
The issue: I've been tasked with designing a passive RFPD circuit, and the grad student talked kinda fast and I understood the words he was saying, but I feel completely out of my depth in building this circuit from scratch. I wrote everything kind of jumbled in my phone notes (my mistake) so it's not a lot to go on. Basically, i'm supposed to take input(s?) from a coherent locking field and a 2nd side-band (probably things I should look up to understand what they mean), and the circuit itself is looking for a peak (meaning graphically?) at a specific MHz, ultimately to, from what I could understand, I could be completely wrong, pick up a beat note. I am unsure if the MHz i'm looking for is the beat note or just the input. The circuit is to have it's own volt supply 5-10V. I am just starting today, so research is my main goal for the next week, as well as familiarizing myself with Python - zero and LTspice for modeling. The output will eventually go to a VCO to go a cavity if it is in the specific MHz.
***Side note he did state that what I have to use to build the circuit is restricted to what is in the circuit lab on campus, so I will have to finagle stuff if they don't have what I end up modeling as what would work if that makes sense, though he did say I could build my own inductor (thats not a problem, I am a geriatric student who used to work at a vape shop when mech mods were still a thing, my coil wrapping skills excellent)
Any help, advice, starting points, resources I'd seriously, seriously appreciate. Thank you to anyone who takes the time to read this and respond, I want to know how to do these things and I want to also understand so I could do my own future projects for funsies.
