Interfacing HMC900 to HMC1197

I am using the HMC900 as a low pass filter before inputting the signal into the HMC1197.  The common mode voltage of the two devices is not compatible.  The minimum common mode voltage output from the HMC900 is 1.5V (5V/2 -1), but the HMC1197 requires 0.45V common mode voltage.  Is there a recommended way to shift the common mode voltage between the two devices.
