My research is under DARPA ELASTx project. The goal of this project is to enable monolithic, ultra high power efficiency integrated circuits. My responsibility in this project is to understand, design and fabricate ultra high frequency, low loss N-way power combiner to combine the power of power amplifier and implement LINC out-phasing architecture.
