they have a lot of different PLL ICs and proper design tools, pretty simple in use.
AFAIK for fast switching PLL, the Fractional-N PLLs are preferable.
However there is a tradeoff:
Fractional-N PLLs generate worse signal, not so clean as integer-N PLLs.

300 MHz step size is pretty far. It is unlikely that you PLL will remain in linear mode going from one frequency to the next. I would start off like this:
1) have a DAC that coarse tunes the VCO to almost the right frequency
2) Sum that DAC in with a wideband PLL loop filter I would go for a 1 MHz control loop bandwidth
3) Look carefully at the VCO tuning port. You will want to eliminate almost all of the capacitance to ground on that port. You do not want a lowpass pole formed there.
4) Screw around with the lead/lag parameters of your control loop filter until you have a slightly underdamped loop (a little overshoot).
Then you are done
