Hi all,  
I want to use the [LimeSDR-USB] to receive GFSK signals at 170MHz, but I have check that the sensitivity is poor on any of the RX paths LNA-L, LNA-H, LNA-W. I would like to get the LMS7002M S-parameters for the LNA-L in order to calculate the optimum matching network for the 170MHz band.  
Could somebody tell me:

1. Where to find the LMS7002M S-parameters for LNA-L? LNA-H and LNA-W S-parameters are also welcome!!!

BR

Orlando
