I am doing project on design of LNA (12 GHz). I am using NE3210S01 transistor manufactured by Renesas corp. (formerly NEC corp.). I using the non linear model of the transistor in AWR Microwave office environment. I have completed the input matching and output matching circuits using lumped element for gain=12 dB and NF=0.7 dB. After that i want to generate Layout of the LNA. But i am facing many problems in this step.
I followed the example given in AWR Microsoft office 2011 "10GHz LNA design". In that design i saw the final input and output matching circuit(lumped+distributed) and got confused.
Why one should use Microstrip line/transmission line in between lumped elements of matching circuit? and How to calculate the length and width?
Also when i saw the final layout of stable amplifier that was completely different. Some additional distributed elements added in that final circuit.
Kindly help me.
