Lists the modifications of the demodulator board D0902745-v4 for high bandwidth operations. For the MC servo, and Common Mode Servo, the slew rate and bandwidth requirements are such that the baseline LIGO RF demodulator design is not sufficient. This set of modifications optimizes the demodulator design for these, and similar applications.
