The MSA-0304 is identical to the Mini-Circuits MAR-3 part.

Have a look at http://www.minicircuits.com/dg03-170.pdf

MAR-3SM
12.5dB@100MHz gain
+23.0dBm IP3
Operating current and voltage: 35mA 5.00V

tnx.
Tried check some noise generator descriptions, although I plan to use
e-b junction of MPS918 and found this good 25 years ago, but I
couldn't find any indication of the RF output level from different
types of sources.
Some noise bridge sources may have an amplifier because - to adjust to
null you need at least 40dB more signal than heard into the RX at zero

My purpose is checking selectivity to compare different boatanchor
receivers in different modes, and I need at least 1mV, so an MSA0304
or two doesn't seem to give sufficient gain...
