I would suggest you to bring the frequency to another frequency
greater than 2 time your maximum audio frequency. If it is not
possible do it in two steps: 2.1 up converter your audio band to
50KHz, clean up the low frequency using a high pass filter than down
converter again to the frequency you want, do not forget to add a low
pass filter after down conversion . Hope this help.
