I am not at my home here I have no tools for analysis. Components values are standard instead of exact. Also as I said my input connected to a 3 meter coaxial cable with an anttenna and output connected to a digital receiver device so I don't know impedance or capacitance of out or input!!!
Hi guys, I am back.🙃🙃🙃 I want to filter above 900 Mhz and below 400 mhz UHF band with a band pass RC filter for a very noisy place, but for some reason it doesn't work, my values was two 100ohm resistor, one 1.8pico cap and one 3.8pico cap. I choose resistor value to 100 ohm because coaxial...
Physical layout is 100% correct just it's not clear exactly like schematic. I didn't use pot and voltage meter panel but Still that are correct microammeter is connected to resistors.
As I said I am not familiar with circuit designing but still I can make simple circuits.
they said it's wrong and go learn, but I know it's not a common circuit but It's working it can detect sources from 1 meter so it's a noise or RF I don't know!
I think it's clear for me, but if you think my circut is a mess then how it can work, if my resistors does nothing then I can remove them!!! Can you explain me how it's working?
Thank you for your advice. I am always learning but it doesn't mean I don't know anything.
It's not a mess. Resistors are essential for my circuit, without them it's not working so there is some function.(one opamp is enough but second one makes it more sensitive).
It's a detector so I can...
Hi guys here is my RF Detector circuit. I am not familiar with circuit designing but I could make it and it's working, it can detect Cell Phone radiation maybe GSM band and a little bit WiFi also electromagnetic waves from power sources and AC lines.
What do you think about it?
Can I improve it?
I know about it but geiger tube are only for gamma and x-rays. I heard about some of RF circuits that they can detect gamma rays also so I think it's possible without giger tubes.
Exactly that's why I am here.
I know it's uncommon but my information is so much lower than you that's why I asked here for finding an answer. It's possible or not.
