This is something that amazes me. I spent 15 years of my career working
next to RF designers. Their standard mixer circuit is still to place an
amplifier stage in front of an active mixer. This is the standard
circuit used in cell phones and other UHF (and higher) receivers even
to this day, even though in the ham community we learned not to do
things that way over 25 years ago. Of course, with all the digital
noise being generated very close to the receiver (and being conducted
into it), they tend not to care about low noise figures in these
devices.
With the general method of commercial design being in this state, it is
no wonder that a couple of hams can actually out-design the so-called
pros.
