[Milsurplus] Raytheon board id

[Glenn Little WB4UIV]

I have a board with cage code indicating it is made by Raytheon.
The serial number (X001) indicates prototype.
The assembly number is G525023-1.
The board number is the same.
It looks to be a power amplifier of some sort with two devices present 
(SRF4053P), large flange mount.
Attached is a picture, if the list will accept it.

Any ideas as to what this is.
Google was no help.

Thanks Glenn
