As far as I know, M/A Com have the 150s in production. I haven't yet tried
their version myself, but I have used several of the 28V fets in production
runs without any problems. There's certainly plenty of demand for the
product line out there, so I hope they will keep it running. Unfortunately,
that hope runs counter to 20odd years previous experience of M/A Com's
support for their rf power products.
