Hi Warren,
It's not strictly the Weaver method but there is an SSB 'up-converter' with I and Q outputs in SL. It actually uses a forward and inverse FFT, and cos^2 windowing (with 50 percent overlap) :

All the best,

Hello the list...

   Has anyone attempted to do a Weaver modulator to generate a baseband

  Looks like it should be possible...
