Note that this is LDMOS. Since we're talking big money, you might as well throw GaN into the mix (Hi Stretchyman!). The maximum die temperature is the same (225 C for both GaN and this LDMOS transistor) and it appears that the costs of both this transistor and GaN might be in the same ballpark too.
I got a chuckle over NXP making a reference design at 27 MHz for this. I assume it's a benchmark for 2-30 MHz performance, but I still got a kick out of a 1500 W amplifier reference design marked specifically for that frequency. "CQ SKIPLAND, CQ SKIPLAND", as they used to say back in the day.
