Hi Tim
it is this amp which I mean:

Actually I dont care too much about TO92 because I mostly use SMD parts
anyways. Using dead-bug technique, they are even suitable for prototypes
and experiments.

Hi
Pulling the output of a normal CMOS gate to ground through a small
resistor is not generally a good idea. That’s what an attenuator or far
end termination of the coax is doing. It’s not specifically outlawed in the
spec, but it’s still not what they are designed to do. Also the output level

Some vendors say "LF-1GHz" etc instead of the misleading "DC".
True DC coupled amplifiers are a different universe. They
must be differential. Search for differential amplifier IC'S
from the usual suspects. You will find that the NF will be
at least 7 dB and up. I'm not exactly sure why, but
Hi
The file you reference is showing a rather complex single mixer setup.
It simply omits the mixer from the schematic. The audio amplifier that is
part of that setup is going to improve the measurement floor by a couple
of db.
With most people saying that it’s way to complex to set up to
Tobias, are you talking about the Wenzel AF Preamp
that uses paralleled JFET's? That uses a 2SK369 JFET which is actually
still in production and distribution and commonly available in TO-92 even.
(Contrast with J310 which was once pure jellybean but today no longer made
new in TO-92!!!)

Search for Wenzel in the Manuals pages on my web site

If you look at the way the power is supplied to and output is taken from an
MMIC there's no way that I can see that they could go all the way to DC as
there's always a capacitor in the output ...
I got all excited a while back when I considered an MMIC for a project because
the spec said
