Low pass filter for Minima
I
need a Lp filter to put after the PA-2008. I made a copy of the original design
and add 2 pcs. off 5v regulator. My relay is 5V. I made simulation of the
filter in ELSIE program. The result from Elsie is to optimistically. Perhaps I should
have use heavier wire in the inductor. If more stop attenuation is wonted, I think
better layout and more shielding is needed.
Here is the ELSIE simulation.
Her is the real result only filter on PCB.
Here is the measurment, in - out of the PCB.
I hope it has been better but here is the
result.
I have run a first QSO, but Murphy is with me, i will come bake, stay tuned.
