Improved marginal return loss of combiner board design with coupler and connector modeling (in HFSS and Genesys) by complex conjugate impedance matching between those and the rest of the circuit. Additionally, explained ripple in prototype test data from off-port termination by replicating the issue in simulation.Main RF engineer on requalification and production of an input network PCB for an ~$800,000 program, successfully shipping all modules on time: resolved various test issues such as test cable phase instability over temperature, port extensions accuracy, calibration errors, measurement variation; Ensured, by modeling in HFSS, that the new production facility's process/fabrication updates, such as plating type & method, would not ruin the RF performance.Supported project on beamformers, calibration network, and auxiliary boards: identified cavity mode issue in layout and interfaced with Sr. Eng. to move design forward; In failure analysis, including X-ray, discovered bond process issue reducing beamformer yield and suggested method to overcome that succeeded; developed circulator test board layouts for evaluating the board next iteration designs as well as the circulator component design; updated Excel test file data mining, lot averaging, and unit tuning.Designed 20-layer board template file to allow for team component designs within the specified board environment – zero mistakes in the file were found in review by other sets of eyes.Shared knowledge with interns, technicians, and engineers on hands-on analysis and software-based design: PCB troubleshooting with VNA methods; realized a ~10x more efficient method for modeling phase tuning passive components over a sweep of possible phase tuning amounts in HFSS and proactively guided multiple interns to implement it in multiple frequency bands; assisted multiple junior engineers in using HFSS eigenmode simulation as a model setup troubleshooting method in their modal simulations of passive components.
