*I've searched through all my catalogs, Digi-Key, Mouser,
*Newark, etc.. and there is no mention of MMIC's in any
*of them.  My question for some knowledgable person(s)
*on the net is:  Where can I find: 1) a source of MMIC's
*and 2) some information, and possibly circuit ideas on
*the pratical application of these devices.  If I knew 
*the name of a manufacturer, I could call on them for info,
*but I'm totally in the dark here.  Can some kind soul
*help me out?

They make quite a variety.  They have MSA-XXXX style part
numbers.  They are very good and cheap.

example:
MSA-1105 3dB bandwidth 50 MHz - 1.3 GHz
3.6 dB noise figure typ at 500 MHz
12 dB typ gain at 500 MHz
third order intercept point +30 dBm at 500 MHz

MAR-X style part numbers.  Very similar to Avantek, slightly 
lower TOI specs.  Cheaper.  I think these are made by Avantek,
but didn't quite meet Avantek's specs.

They are very easy to use.  They require input and output DC
blocking capacitors and a DC bias on the output (with a resistor
and maybe an inductor).  They are 50 ohms in/out.

Higher gain parts have exellent noise figure, but poorer flatness
and TOI.  Low gain parts have worse noise figure.  They are very
stable devices.
