Gms = IS21 / S12I for k < 1; Gma = IS21 / S12I(k-(k2-1)1/2) for k > 1. In order to get the NFmin values stated in
this chapter, the test fixture losses have been subtracted from all measured results. OIP3 value
depends on termination of all intermodulation frequency components. Termination used for this
measurement is 50 Ω from 0.2 MHz to 12 GHz.
