They have some interesting stuff.

It will make you very depending on their products.
MiniCircuits has been pretty good. Parts lifetime is a chronic
problem
in our business.
Sure, but in my time we needed at least one second source for
components we used.
Mil would require that too over there?
An other thing that makes me wonder is the 50 Ohm issue
At 1 GHz the wavelength is 30 cm
If this was to sort of \'appeal to people to
just chaining blocks together on a PCB with 50 Ohm transmission
lines in between\'
then its silly.
In many of not most cases the parts can be more efficiently used
with a different coupling impedance
when a few mm apart even more so.
Then it is RC times or LC[R] coupling (thinking RF now) that can
be optimized.
Done it many times .
So who is it for, the RF clueless?
No, it\'s for broadband amplifiers, (near) constant gain over GHz
bandwidths.
Jeroen Belleman
Ever looked at the Y amplifiers of a modern GHz scope?
Not in detail, no. How do they do it?
Jeroen Belleman
Google tektronics circuit diagram
Lots of vintage circuits, which I *did* see before. Interesting, but not
modern. Can you be a more specific?
In those vintage circuits did you see any minicircuits like stuff?
Max frequency was?
We were talking about mini Circuits RF gain blocks, easy to throw
together. There\'s nothing silly about that. You brought up scope Y
amplifiers, which have a completely different purpose and a completely
different architecture. Now what was your point, exactly?
Jeroen Belleman
The main issue with most of MCL\'s packaged amps is that their gain rolls
off steadily. Put a few in series with no peaking networks, and the
results can be very disappointing.
I\'ve used RFBay for higher-performance things, with excellent results at
good prices.
