Re: LNA DESIGNING
Hello sarkar,
The procedure for LNA Design from Specifications all depends upon implementation of the LNA & the Method or EDA tool used...
Say for example for MMIC LNA design & Hybrid MIC LNA some of the steps differs...
Again the availability of the model S-parameters or Nonlinaer spice model...
Start with the the device analysis, such as Stability, input,output reflection coefficient measurements, Gain, Noise Figure then choose the Stable network for the device if unstable...
Then if it is non linear device Bias the deice using biasing netork (if S-parameters no need since it is measured data at perticular bias conditions)...
Then finally build the matching network from input to get better Noise, & Gain...
Plot all other measurements such as VSWR, Impedance, etc...
Build the layout & export it as DXF or Gerber...
