[Amps] Freescale LDMOS devices

[Paul Decker]

I don't know how the freescale parts are, but the NXP BLF578XR seems to be holding up well for me.  with 4 watts I can drive it to about 1450W output with 52V @ 42A.  I've been running it ~45% duty cycle 45s on 75s off with wsjt on 2m without issues.

John, sounds like a great commercial project with quite an end result 
most Hams will never see.  I am very curious about your testing.
Be very interested if you had any fault history for the MRFE6VP61K25H.  
Have you pushed it to extremes.
