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

Are you looking for an RF/Microwave engineer who can turn your measured S-parameter data into a reliable system-level efficiency study inside AWR Microwave Office before hardware fabrication? I’m an Power Electronics/ Pcb Design Engineer with 5+ years of experience in microwave circuit simulation, PA characterization, matching/balun integration, and system-level RF analysis. I can import and validate all measured S2P/SNP datasets, organize them into a clean hierarchical architecture, and build a simulation-ready power-stage chain that mirrors your physical implementation. Scope I Can Support • Import and verification of transistor, passive, and coax-balun S-parameter datasets • Hierarchical AWR schematic creation with packaged transistor and idealized bias networks • Fundamental-frequency and bandwidth sweeps for PAE and drain efficiency • Pout vs Pin, gain compression, stability review, and S-parameter analysis • Optional load-pull assisted optimization for efficiency-focused tuning • Clean annotation of coax balun topology and signal flow Deliverables • Complete AWR project file with linked S-parameter references • Annotated hierarchical schematic • Simulation plots: Pout vs Pin, Efficiency vs Pin, S-parameters, stability, and load-pull contours (if applied) • Short PDF summary covering assumptions, setup, tuning approach, and headline efficiency results I can start immediately and maintain close communication throughout validation and tuning.
