Hello, Mark !
You can design an LPF and then multiply it's taps by the
complex sinusoid exp(j*w0*t). This will result in a two sets of
coefficients (real and imaginary). Each set represents a BPF
centered at w0, but the two filters will have 90 degree phase
I use such technique in my HF DSP transceiver design.
All the best !
