Authored over 20 internal papers and presentations covering design of LDMOS PA stages, Doherty PA design, evaluation of SiC and GaN RF power devices, evaluation of competitive LPA products and PA modeling using ADS. Participated in cross-functional team solving RF Computer Aided Engineering (CAE) tool issues and managing RF CAE tool contracts. • Developed, promoted and trained engineers in linear PA design methods and modeling tools, improving PA design robustness and shortening design cycle-time. • Built strong relationship with RF power transistor suppliers (Motorola and Freescale), producing industry leading PA performance at lowest cost. • Developed and implemented high-efficiency Doherty PA design, avoiding need for production tuning found in previous Doherty PA designs, becoming basis for most future high efficiency linear PA designs. • Co-developed and initiated Envelope Tracking technology, improving PA efficiency up to 40% in Land Mobile Base Stations, where required operating bandwidth too large to permit use of Doherty PA technology. Incorporated in latest generation of high-tier Land Mobile Base Stations. • Co-developed and demonstrated PA linearization system, achieving 80 dB suppression of distortion products in multi-carrier linear PA.
