LNA design in Ku band is absolutely critical task.That's why, I suggest you read some textbooks before starting this task.
Because simulators are only mathematical tools and they don't do the designs by themselves.
Choosing the right active device, studying on this design in terms of stability, available power gain, matching considerations etc. are the main steps toward to a professional design.
Therefore, theres is no such rule of thumbs about a "design", every design has its own charateristics,methodology,design steps and forms.
