Sigma Studio IQ modulator/demodulator

I'd like to use the SigmaDSP for IQ demodulator (and in the future for modulator). I'd like to create a 90 degrees phase shift block (AF -> 300-3000Hz).

Have you got any idea how can I do this?

(My idea is too difficult and not too elegant - I can crate many (10-12 pcs) filters and delay blocks. I hope you have a simplest solution).
