I am designing an amplifier at 12ghz using infineon part cfy25.
I used it's s-param for design,but did not get the desired performance after fabrication.
I am having concern the way ,the manufacturer has extracted these s-param for this device,on inquiry he has informed that,he has extracted this data after mounting device on a PCB and choosing reference planes at device lead edges.
When I simulated this amplifier,I considered package edges as reference.
Please give suggestion,for using this s-param data correctly in simulation.As additional device lead lengths of 1.5mm on each side,will spoil the performance of amplifier,if not accounted properly.
