I want to use a coaxial resonator as the IF filter at 500MHz. The resonator will be made of copper, with no special treatment, maybe not even silver plating.
What selectivity can be expected from this?
The frequency stability on the long term and with temperature variation of 10-40°C is good enough for an IF filter, or it needs to be tuned periodically?
