crystals temperature frequency
Hi Guys
Can any of you explain how the cell phone industry get a very fixed frequency transmitter? I am doing a system which need to generate a signal at 2.2GHZ without temperature sensitive from 0 C to 40 C? Can anyone explain or give me some sources how to generate a stable frequency transmitter? I heard it seems to come from a extreme stable crystal to use PLL to generate the stable frequency. I hope someone can explain it more to me.
Thanks a lot,
B
