Hi

have some problems to find data for MMIC MSA0304,
only need to know the bias resistor for Vcc=9V and/or 12V, IP3 and
gain

need it for a general purpose noise source with MPS918 to cover
500-25000kHz band for selectivity tests. The reason for using this old
device is that I already got some douzens

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
