We built a PA for the high band VHF Micor using two Mitsubishi modules. We had some problems getting sufficient drive out of our exciter conversion and we wanted higher power, so we used two modules requiring 50 mW input for 35W out.
Turned into a real challenge. Using an RF splitter to divide the input and a phased power combiner/bridge to sum the outputs, we manged to get a very stable and bullet proof PA that once transmitted all night due to a controller malfunction. The heavy duty heat sink and a fan allowed the brick on the key operation with no problems.
