Dear all,
Have anyone here have some experience b4 of tuning the crystal filter center frequency?
As we know, the crystal filter has a very sharp passband bandwidth and very high Q. While, the crystal filter is also very hard to tune the frequency you want. I want to have a crystal filter at frequency 27.27273Mhz, while the crystal at this frequency is really hard to find. The closed crystal I could find is 27.3MHz.(By the way, I do not have the crystal on my hand, I do not know the exact resonance frequency)
So can I ask anyone who could share the experience with me of tuning the crystal filter.
Many thanks!
