LTC5583 detector voltage is not coming as expected



I have used the part LTC5583IUF#PBF for Dual RMS power detector for the operating frequency of 4.4GHz to 5GHz operation.

I have used Test Circuit  Differential Input Configuration (page no. 16 in Data sheet) frequency 5800MHz for my applications.

 RF Input Power level is -20dBm

I got the VOA voltage level 0.9V @ 4.4GHz and 1.01V @ 5GHz

               VOB voltage level 1.21V @ 4.4GHz and 1.1V @ 5GHz.


Why these 110mV variation over the frequency range and also not getting same variation on both outputs?
