Contest LNA EME 2014  in Pleumeur Bodou - FRANCE

NF Measurments by Pierre-Franois F5BQP and Sylvain F6CIS   

Ref ENR : Micronetics NS346AK CAL 07/2014  and   HP 436A CAL 06/11/2013

Some LNA  have been tested by Jean-Franois F1LVO on his VNA HP 8720B at power input DUT : -30dBm

To avoid any discussions for the contest have been considered only the LNAs which where unconditionnally stable

NF (max) = some tests have been made + Circulator/Isolator with > 28dB RLs and band width and also using a 0.25 wl cable with the INS correction on the noise head obtained from a comparison (Nb. loss have been included into the CAL of the setup)

We apologize not been able to measure LNAs above 1.6GHz due to a failure of the preamplifier 70620B opt001 of the initial MMS 70k configuration during the workshop installation
