Hi,
Elbadry is right, there is a possibility to use a single polarity supply.
See Figs. 25 and 28 in Page 8 of the data sheet of this IC here:

The solution is to provide the correct bias currents (by resistive voltage dividers) to the base inputs of the Gilbert cell transistors. Because these inputs are the open bases of the transistors without any internal bias supply connection.
Notice the 1.3 kOhm-820 Ohm-1 kOhm voltage divider between +Vcc and the Ground. They provide the correct bias for the bases.
Notice also that that Pin 5 of the IC goes to the +Vcc via a 10 kOhm resistor in these two Figures, while in the split supply case it goes to Ground via a 6.8 kOhm.
Study Fig. 23 for the internal schematics too.
There is an application note here but of course you can find lots of other circuit in the web by searcing for it: h**p://www.onsemi.com/pub/Collateral/AN531-D.PDF
