rx nf

beacuse the LNA is used balance design in rx, how to calculate the system NF.Generally the Function NF=NF1+(NF2-1)/G1+(NF2-1)/G2+...;
now how to calculate NF1, G1, when LNA is balance designed.
 

nf1+(nf2-1)/g1

to calculate this balance LNA NF, you only need add the hybrid NF(insertion loss) to the equation.
