Hello,
I suggest the LPF with
- pass Band Frequency about 10MHz
- filter type LC Butterworth, 9th order
- pass power 80W (Vpp 50V)
As inductor use iron powder toroid core T130 with material 2 (Red/Clear) or 6 (Yellow/white)
The question is what to use capacitors?
The ideal would be silver mica, but they are poorly accessible and very expensive.
What used instead of silver mica? Preferably any in SMD
It is feasible to use paralel combination of ceramic capacitors?
For example,one 300pF replace, 3pcs 1206 NPO 100pF in parallel and that improve Q factor ?
Thanks you
