HMC903 LNA: Input return loss and noise figure

Hello ADI support.

I have the HMC903 evaluation board (128395-1) and measured it on a calibrated VNA.  Vdd1=Vdd2=3.5 V.  DC current was 79 mA.  I measured about 10 dB input return loss at 10.5 GHz.  I would like to improve this return loss with external matching.  Does ADI have a S2P file with noise data for this part?  If not, has anyone there matched the input and if so what did that do to the NF?  I can work on this myself in the lab but thought I would first ask the question.  Thanks.
