We would like to hire someone to design (no PCB needed, only schematic but the simulation needs to be as accurate as possible) a crystal notch at a specific frequency (in the MHz).
We already have the quartz, we also have every parameters of each piece (Fs, Fp, Cs, Cp, Q, Rs ...)
This filter needs to be matched at 50ohm IN and OUT.
Attenuation should be at least 90db.
Maximum Insertion loss : 6db
Min Bandwidth : 1kHz
We have some measurement instruments if needed : VNA, Spectrum analyser, oscilloscope, crystal measurements ...
