About Jin Shao
Bringing RF expertise to the edge — where AI and FPGA are redefining wireless intelligence.Edge AI:Trained CNN & ResNet models (RTX 5070 Ti) for RF modulation classification (QPSK / 16QAM / 64QAM) with simulated real-world impairments — phase noise, IQ imbalance, PA saturation, multi-SNR. Deployed & benchmarked classification accuracy and inference latency on NVIDIA Jetson Orin Nano (TensorRT) and Xilinx ZCU104 MPSoC (Vitis AI). Tools: PyTorch · TensorRT · Vitis AI.FPGA/DSP:Designed DSP logic prototypes in MATLAB using Q1.15 fixed-point format for bit-true RTL alignment. Verified in QuestaSim with SystemVerilog coding, validating bit-true accuracy across all signal paths. Implemented offline hardware-in-the-loop (HIL) on Xilinx ZCU104 (Vivado · Vitis), with MATLAB-based I/O comparison. DSP blocks: CFR (Peak Cancellation) · Digital AGC · CIC with Compensation FIR · Matched Filter / Pulse Shaping Filter.RF:10+ years of industry RF engineering experience since Ph.D, specializing in GaN Doherty Power Amplifier (SSPA) and RF Front End design for 5G mMIMO and aerospace applications. Expertise spans full RF Front End development — circuit design, MMIC/RFIC integration, and laminate layout. Tools: RF System Simulation (AWR VSS) · Harmonic Balance (AWR · ADS) · EM Simulation (ADS Momentum · HFSS) · Layout (Altium · ADS Momentum). Proven track record: Blue Origin · Qorvo · Infineon · iCana. 1 U.S. Patent · 20+ publications · 941 citations. GaN Expert (Qorvo). Ph.D, RF/Microwave Engineering.
