[MRCA] RBA RBB RBC receiver multicoupler

[DSP3]

As I seem to recall, the operational signal levels in the video amps we 
used in satellite data distribution was typically 2vPP.  That's a 
healthy signal level compared to an HF receiver's input. These amps are 
used in a shielded environment so spurious signals generally are not 
present.  I do not know how their small signal handling capability would 
be nor their noise figure.  At signals less than say -100dBm or -115dBm, 
I wonder what they look like?  Might work... no harm in trying.
