Depends on what you mean by SSB modulation.
If all you want is is the same effect as an SSB transmitter with a 1khz tone into the mike,
most any RF source can do that.? As in any CW transmitter, or one channel of the si5351.
I would think two tone SSB modulation could be correctly simulated by summing two channels from the si5351.
Obviously, the si5351 emits a square wave.? If you care about the harmonics, will need to have a different LPF
for each octave of interest.
If you have a pressing need to hear voices, then that's pretty much half of a uBitx.
If you don't need 10 Watts, then can?strip out the entire power amp from Q90 on out.
May or may not feel a need to include the transmit LPF's to reduce harmonics.
And perhaps revisit a couple months worth of forum posts about spurs and mixer levels and such.

What I would really like is a wide-band frequency source with SSB modulation ..I've got several AM modulated signal generators, but I've never seen one with SSB capabilities ...What sections of the ubitx would be necessary for such a beast?
