[Amps] Question about SPE 1.3K-FA amplifier

[Kevin Stover]

All of the LDMOS devices that I have seen are the twin cores in One 
"device" or package.
The LDMOS packages I'm aware of have a max dissipation rating of 1200-1250W.
The amp may have passed FCC harmonic testing thanks to a real good low 
pass filter but I'm pretty sue they don't test IMD nor do they test to 
see how long the devices last running above the dissipation rating.
