Hi guys,
I'm new here and I am asking your suggestion to solve a radiated emission problem that's afflicting a device I am working on.
I am facing high radiated emissions from a quartz running at 20 MHz frequency (checked that the quartz was the emitter using a sniffer antenna) and the frequency the device "over-emits" at is 160 MHz. I tried increasing the capacitors value connected to the quartz as to smooth rise time but, apparently, it hasn't worked the way I wanted to. Is there any other trick I could count on (consider that I tripled tha capacitors value without affecting device functionality)?
Do you think it could work if I continued to increase the capacitors value? What if I placed an emission absorber tape over the component? what do you think it could be the most cost effective solution?
Thanks in advance for your suggestions!
Giulio
