I used microwave office for the design. I haven't used that in a while but I remember there being a Lange coupler element.
I simulated the linear response only with the S-parameters provided by the manufacturer, Avago ATF-34143 transistor.
This model has the noise match for the input. I was making a low noise amplifier, this data tells you how to absorb the noise that comes backwards from the gate so it does not reflect back into the input of the amplifier and increase the noise figure.
My design was from 800 to 2000MHz and VSWR was <1.3:1 across the band.
