Bruce,
The MRF-150 came out in 1983/84 and Helge Granberg produced the Motorola
app not EB-104 using the XRF-150 in the same year. It is still readily
available. Be careful with your FACTS!

FACT... Because we can not see into the future, we only have history
to look at.
FACT... History has shown us that RF power devices have NOT survived
15 years of manufacture very well... IN FACT... I challenge you to
show me the facts. Show me a solid state RF transistor in that power
class (RF 1400 watts out) that has been in production for 15 years and
is still in production today. I am open minded and would love to see
your report.
FACT... I noticed that you did not mention if they agree to the $100k
Guarantee. Why is that important, see below.
FACT... If they are sure that they will keep production going until
the year 2032 (15 years), then that guarantee should BE NO PROBLEM for
them. Talk is cheep
FACT... If you feel that is an unfair request, then that tells us that
(Deep down) you do not believe them either. Please do not tell me that
you DO have a crystal ball.
FACT... Many high power tubes (8877 and 3-500) do have a rich 40+ year
history with no end in sight.
FACT... I have purchased the BLF188 because I CAN afford both the cost
and the risk. However people who can not afford the cost and risk may
wish to take this into consideration.
FACT... I have been in the RF repair industry since 1971 and have seen
and faced this issue happen over and over again. How long have you
been in it???

Actually they have put it in writing, on the data sheet (although
prelimenary at the moment) they state 'Included in NXP product
longevity program with assured supply for a minimum of 15 years after
launch' which I see as a quite firm commitment. Or do You have an
example that NXP has not fullfilled their 'longevity program'
commitment for some components?

they will put a penalty clause stating they will give you a $100k
payment should they fail the 15 year test. After all if it was true,
they should have no problems with that. On the other hand if they
baulk , that tells you that they are just talk with no truth.
Additionally, Please be honest... If you are reluctant to ask them
for that guarantee, that shows that you KNOW they are just talk.
Someone or Anyone let me know if anyone gets that guarantee.
Remember company plans do change with new management or when they get
a bad P&L. This is especially true if they are listed on any exchange
such as NASDAQ. Like the dip in early 2016 (NXPI at $65) and now back
on a good clime this year ($109.00) now. companies tend to make
strong claims on the peek and pull claims back claims on the stock
dip. Often they have no choice. The device market history is the only
good indicator. Solid State RF power devices still have a very poor
history. Translation... the market speaks with authority, companies
just talk.
I have a solid state amp (dual BLF188) homebrew amp, and have two (2)
tube amps one of which is AL-1500 with 8877 tube. I love them all,
but understand the risk of SS replacement as I have been in
broadcasting or the RF repair business since 1971 and a Ham since
1962. I have lived through everything that I have said above.

I recently took part in a webinar on the new, 1800 watt, 65 volt, LDMOS
transistors made by NXP. It is the MRFX1K80, and NXP plans to produce
it for at least 15 years.
