- Design and develop high-power RF transistors based on LDMOS or GaN technology mainly for the wireless infrastructure market. Design work involves low impedance transistor matching networks with the use of low loss integrated passives, wire bonds, MOSCAPs, and packaging interfaces.- Work closely with device, product, modeling and packaging engineers as well as manufacturing personnel for successful and timely product design and introduction.- Develop transistor models for designed products. Models are validated to measured data and provided to customers for their design use.
