Hi
…. or you could do a milled box inside a milled box inside a milled box.
Isolate each one from the others. Filter all leads at each “goes in” and each
“goes out”. Put the input side in it’s own cavity in each box. Put the output
side in it’s own cavity. Put the control signals in their own s
I should mention that the input supply filtering to the DC-DC converter
should have good attenuation at the switching frequency, but not at low
frequencies, so there's no need to get carried away with the size of the
filtering at the converter input. Too much filtering, especially
inductance, c
Yes, for best quietness, you definitely should "can it up" in a metal
box, and use feed-through caps for all the I/O, including the commons or
grounds. You have to figure out also where all the currents flow, and
contain the loops. With sufficient L-C filtering on the input and output

Look at their TVN 5WI instead ?

Not entirely on subject since this is for a transceiver, but figured
this would be the group most likely to generate a useful answer.
I happen to like the older Icom IC-271H and 471H, I have a pair of each
where one is currently the control and one is the in-progress unit.
