ADL5801 Component Selection for DC Operation

I want to use the ADL5801 to do upconversion.  My RF will be 300MHz, LO = 2.7GHz, and my output IF would be 2.4GHz.  I've tried following figure 32 on page 14 of the datasheet (copied below), but the noise figure I'm getting with the components I chose is horrible.  However, I did not include L3 or C13.  Is there a set of equations or a spreadsheet to calculate the desired component values?
