By performing the K-∆ test for a given transistor the values of K and ∆ were found to be equal to 0.383 and 0.334 respectively. The transistor with these parameters has unconditional stability.
If the S parameters of a transistor given areS11=-0.811-j0.311S12= 0.0306+j0.0048S21=2.06+j3.717S22=-0.230-j0.4517Then ∆ for the given transistor is:
The condition for unconditional stability of a transistor as per the K-∆ test is │∆│> 1 and K<1.
For any passive source termination ГS, Unconditional stability implies that:
If │S11│>1 or │S22│>1, the amplifier cannot be unconditionally stable.
