Resume available upon requestSummarySmartphone RF front-end system architect and systems engineering leader with a record of creating market leading solutions through innovation and system modeling to extract new system benefits. Accumulated many years of system expertise and innovations in the portable and cellular industry where stringent requirements such as: low cost, small size, low voltage/current, and high performances must be met simultaneously. Developed multiple math models of DCDC converters for APT and ET, PA (power Amplifiers) and tunable frontend systems, along with architecting and system designed many RF Frontend components that have sold in billions of units so far. Learned about SAW filter design, including duplexers, quadplexers and other custom filters. Most recent focus has been on the study and simulation of mixed technology filtering topology for 5G and Wi-Fi 6E, supporting multiband broadband or digitally programmable solutions. Core CompetenciesExcellent work ethics and discipline for “work from home” or unsupervised and remote collaboration. Demonstrated collaboration across engineering organizations. Excellent communication skills with customers. LTE 4G/5G & Wi-Fi 6/6E RF front-end systems engineering. Tunable RF systems. Analog and digital closed and opened loop control systems. Power amplifier (PA) architectures and power supply systems for ET and APT. ADS, Matlab, Mathcad, System and production yield modeling.

• Developed new component opportunities by identifying system and architecture alternatives using Newlans tunable high-Q capacitor and enabling more efficient, performing and frequency agile RF front-ends.o Carrier Aggregation (CA) and coexistence tunable notcheso TRX diversity and MIMO (2x4 and 4x4) tunable phasing and matching networkso Tunable filters and duplexerso Next generation Power Amplifiers (PA) for APT and ET, as well as supporting uplink CA (2X)o Tunable SAW/BAW and FBAR filterso Impedance tuning for Antenna and other applications• Investigated the impact and benefits of the high-Q tunable capacitors on Power Amplifiers output and interstage matching networks.o Increases the “efficiency bandwidth” figure of merit beyond traditional fixed-tuned PA’s and reduces post-PA losses for overall higher system efficiency.o Taking PA waveform engineering to the next level with digitally controlled harmonics manipulations and enables higher efficiency PA’s operating classes like E, E-1, F, F-1 to be improved beyond current fixed solutions.o Created the “Direct Connect” PA architecture that eliminates the need for a DCDC converter and offers PA efficiencies that are 10 to 25% higher than today’s best in class PA’s• Defined and modeled (ADS) newly architected RF frontend elements to estimate performances benefits and create system IP:o Noise reduction techniques, RX Diversity modules, waveform engineering for ET and APT PA’s, tunable notches and filters.
