Make a custom Sparameter.s2p file.
Step 1 : the Sparameter.s2p template file.
Step 2 : Open the Sparameter.s2p with a text editor.
Step 3 : Replace the value of the Freq., Mag., and Ang.
with your device S parameters
Step 4 : Save the file and exit.
Step 5 : Browse and submit your new Sparameter.s2p file.
A convenient way of expressing the sufficient conditions for stability of the microwave amplifiers is stable factor (`K`) and `|Δ|`.
When `K` > 1 and `|Δ|` < 1 that the amplifier is unconditional stable.
The maximum transducer gain under simultaneous conjugate match in this condition is called maximum available gain (MAG).
On the contrary, when `K` < 1 and `|Δ|` < 1 , the amplifier is potential unstable.
The maximum stable gain (MSG) is defined as the value of maximum transducer gain when `K`=1.
`K` : Stable Factor
`G_(T,max)` : Maximum Available Gain(MAG)
`G_(MSG)` : Maximum Stable Gain(MSG)
`K= (1- |S _11 |^2 - |S _22 |^2 + |∆ |^2 )/(2| S _12 S _21 | )`
