I've searched this space looking for a decent RX/TX SDR that does a few watts. It's surprisingly hard. Seems like the 5 watt $30 HTs (that are SDR based) are extremely common, but as soon as you add any flexibility it's $1000s.

Those two constraints are easily separated. Radio and separate power amplifier. You will find that a really wide band power amp is expensive so a lot of people will have two to five PAs and an RF switch to select between them
