A couple of tech tidbits from N6QW
https://n6qw.blogspot.com/2024/03/march-25-2024-mmic-amplifiers.html
Here Pete mentions MMIC amplifiers but the tidbit I gleaned was that Digi-Key now sells Mini-Circuits parts. Previously it was either buy direct from Mini-Circuits or from ebay or other sellers. Which was fine but often a big shipping cost would be spread over just one type of item. But now it's easy to add something like a genuine ADE-6+ mixer to a normal Digi-Key (or Mouser) order along with other needed parts:

BTW, the ADE-6+ specs look interesting (another tip from Pete) - although more expensive than the usual ADE-1, the ADE-6 is spec'd to 50 kHz where the ADE-1 is only spec'd to 500 kHz. Must be different cores ? Also, even though both the ADE-1 and ADE-6 are surface mount they are easy to work with due to fairly large-ish size and lead spacing.

In this post Pete mentions dual gate MOSFETs and workarounds but the tip for me is that ferrite cores from Fair-Rite are also now available from Digi-Key. I had bought previously from Mouser but it's nice to get them at Digi-Key as well.

If only the powdered iron cores from Micrometals were available from Digi-Key or Mouser !
