AWR RF Power Amplifier Simulation
Budget: $50 – $0 USD
I have a complete set of measured S-parameters for each active and passive element in my power-stage, including the coax-balun network. I now want to see how the whole chain behaves before committing to hardware.
Please load the data into AWR Microwave Office and build a hierarchical schematic that mirrors the real layout (coax baluns on the input and output, packaged transistor in between, bias networks as ideal blocks are fine). The key figure of merit for this study is overall efficiency, so I’ll need swept PAE and drain efficiency plots at the fundamental operating frequency as well as over a small bandwidth. Gain, stability, and any obvious linearity issues can be checked, but efficiency must drive the tuning.
Deliverables
• AWR project file with all S-parameter blocks correctly referenced
• Annotated schematic showing coax balun implementation
• Simulation graphs: Pout vs Pin, Efficiency vs Pin, S-parameters, load-pull contours (if you use them)
• Short PDF memo summarising setup assumptions and the headline results
