Default Looking for M67715 PA Module

I realize it hurts when you can't just plunk in a part but
in the end you'll feel better, honest..

I think we are possibly talking about different MOSFET modules. The one
I specifically refer to for use at 1240-1300 MHz (RA181213G). The data
sheet says it is designed for FM (NON-linear) but can be set up for
linear use by setting Id with Vgg and controlling the output level with
the input (RF) level. http://www.rfparts.com/pdf_docs/RA/RA18H1213G.pdf

It should work...it will just require a few additional components.
