[Amps] New NXP BLF578XR 1200W LDMOS FET is "indestructible"

[Al Kozakiewicz]

Perhaps, but part of what keeps an RF vacuum tube price high is the amount of skilled labor required to assemble and test it. Even if the value proposition was zero, the incremental manufacturing cost would still be significant.

The incremental cost of manufacturing semiconductors is very low.  On the other hand, there is far less demand for RF devices than cell phone chips or computers...

Since most power RF transistors will blow if you even look at them incorrectly, and a tough device adds a lot of value and eliminates some of the required protection devices I'd venture that the price point for the device will be in the neighborhood of a comparably rated vacuum tube + or -.   ‎

And no price ....

I would still try it at 160m ...
