Has anyone seen a solid state relay that will switch a signal of 2-3 MHz at speeds of up to 1KHz?
If not, what would be the highest practical limit for this type of device?
The intent is to produce a crude modulated signal.
Continuous duty rating would need to be about 30 watts.
Thank you for any pointers.

You're basically looking at a mixer. You could try to build one yourself with a set of power shottky diodes. Make sure to consider what happens with the reflected power.

The limitation is not the speed, it is the 45dBm power level. You will have to go custom or shell out big bucks for a niche market switch. From your description, it is understood that you have a single channel that is turned on and off- sounds pretty simple.
Sounds pretty easy. Look at CEL.COM for the NEC ssr's. At your speeds, expect some asymmetry of on/off switch times and a bit of off-state feedthrough from capacitance, but "crude modulated" won't be hard.
