What are the basic components of an RF transmitter, and there
respective roles ? (I'm learning electronics so excuse the
newbie-language!). Any help would be great.
Transistor(s) - used to amplify the signal ? Possibly what else?
Resistors - to limit current entering transistor base, collector and
biasing ?
Capacitors - ??? filter out higher frequencies than needed? Why are
caps sometimes connected to the collector of a transistor?
Crystal - I understand the concept of this, i.e. say 27 Mhz - does it
filter the inductor frequency to precisely what the crystal is labelled
at?
Inductor (which antenna eventually links to) - does this generate radio
frequency (which must then be amplified by transistors)?
Signal Diode - ?
Sorry again if I sound like a newbie, I'd like to learn as much as I
can bout RF circuits.
Any answers would be appreciated.
Thanks,
Andrew
