Folded cascode LNA
hello. I'm a student working on the folded cascode LNA designed by my senior to work on 2.14GHz. the LNA have been fabricated and the chip is measured. the S-parameters measured shown some deviation from the desired spec. I am required to do optimization on the design based on the measurement result.
But i have not experience on interpreting the measured result and don't know what is the reasons that cause the S-parameters vary from the desired based on the result. can anyone help me? I have included the measured result. thank you
