Thanks,

Please define "quadrature conversion". As far as I understand,
quadrature modulation is a mapping that takes k bits at a time,
and outputs one of 2^k possible complex-valued number.

Some others may take quadrature modulation as one of the next
steps, which is taking a complex-valued signal, multiplying with
exp(j 2 pi fc t), and taking the real value.

Which do you mean?
