Here is an idea from another site:

Don't run at the max rated output power of the device. Back off by 25%, 33%.

Make sure the device is running efficient (65 to 70% min DC to RF efficiency).

Tune for efficiency rather than max output power or gain.

Lower the supply voltage. This is very effective - running a 28V device at 24 or 18V volts will greatly increase its' chances of surviving a severe mismatch.

Make sure the device is adequately cooled - big heatsink with a big fan, plus a thermal cut-out on the supply if things get too hot for any reason.

Use a current limited power supply, and set the current limit, so if you're drawing 5A at 28V, set the limit for 6A.
