ADF4350 using its 3rd harmonic output

In my project I am tripling the ADF4350 output frequency using a MiniCircuits frequency multiplier.  But it occurs to me that I might just as well high pass filter and amplify the direct ADF4350 output to remove 1st and 2nd harmonics and thus dispense with the tripler.  Is this good practice?  Can I rely on the ADF4350 having stable and rich 3rd harmonic output right up to 3 x 4400MHz = 13.2GHz ?
