Many of us know a lot about Receivers & Transmitters.Ok so I look at these links and I cant tell you how confusing everything looks. I'm currently going to niagara college and the only thing I've learned in RF is the topology of most transmitters and receivers. I understand there building blocks on what each part does but nothing on designing them and putting it all together to make a receiver or transmitter. I feel like rf is out of my league how long did it take for you guys to design one? What kind of education did u get to design one? Are there online courses i could take?
Wait! There's more!!So I started looken at VCO's typically using the colpits fprmat with the use of a varactor to control the frequency. I've attached the picture of the circuit im analyzing.
What I understand is the Varactor and Inductor determine frequency, C1 blocks DC but what I dont seem to get are the other 2 capacitors from the base to emitter, I know they give the circuit feedback that keeps the oscillator going but what values do you choose for them?
Thanks in advance
