I wonder if a high power transistor could mount on a chill block sold
for puck type very high power devices. For instance,

Of course, getting the RF into and out off the device with this cooler
in the way is tricky.

With water cooling, why not sit the transistor over a pocket and
run the coolant directly against the flange? That's a method I saw
in production test at the Philips (as it was) factory.
NEC had an ill fated TV broadcast tx which cooled the transistors
with compressed air blown directly onto the flange. In terms of
cooling I was told it worked just fine, the problem came when the
nozzles blocked with dust.
