Single balanced mixer ssb generation?

It balances out the carrier so it produces DSB. You could use it as part of a phasing type SSB generator.

That is what I thought too. The output filter is not addequate for sideband filtering, despite what the article says.

Have you gone through the calculations to determine that the filter is not adequate?

No I have not done any calculations.
From my experience I think a single LC is not adequate in filtering out the opposite sideband.

Is it anything that you see in the circuit that I miss, that supposes that the filter should be adequate in attenuating the opposite sideband? (even not many dB, but just to be enough for ssb comunication)
 

It might work (but not very well) if the tuned circuit were tuned to 30 Khz and was of very high Q.

But 30 Mhz is laughable.
