Note:
Maximum Available Gain and Maximum Stable Gain are defined by the K factor as follows:
MAG = |S21/S12(K ± sqrt(K2-1)) |, if K>1, MSG = |S21/S12|, if K<1
Table 5 lists the electrical characteristics measured on evaluation boards tuned for typical application
frequencies when Rbias is 1.2 k Ω . Further details on the application circuits are shown in Section 3,
