Full Job Description Responsibilities:
Conduct original research leading to the design, mathematical modeling, and experimental validation of a high dynamic range, low-noise differential mixer using SiGe microwave transistors. Develop transformer-free, single-ended-to-differential RF stage architecture that enhances signal integrity and integration efficiency in active mixer topologies. Formulate and implement dual-feedback linearization technique that significantly improves mixer linearity, dynamic range, and noise figure. Perform comprehensive noise and gain modeling of active mixer stages, integrating analytical and simulation-based methods for precise noise figure prediction and validation. Design and optimize a Marchand balun structure for the local oscillator signal, validated through 3D EM simulation and experimental measurements. Develop and fabricate a multilayer SiGe PCB prototype, achieving excellent
LO-RF-IF
isolation and confirming simulation-to-measurement correlation across 0.5-1.8 GHz.
Qualifications:
Bachelor of Science Degree in Electrical Engineering or Equivalent Work Experience Over five years of experience in designing and developing RF microwave products like 90 and 180 hybrid couplers, power dividers, multi-couplers, phase shifters, modulators, filters, transformers, and attenuators for commercial platforms. Over two years of experience in designing LNAs, Power amplifiers, RF amplifiers, and active RF Mixers for trans-receiver systems. Proficiency in RF concepts, Telecommunications RF Infrastructure, and radio design theory Solid understanding of RF, analog, and digital circuits. Skilled at using network analyzers, spectrum analyzers, analog and digital power meters, signal generators, vector network analyzers, phase noise analyzers, etc. Expertise in interpreting technical drawings, documents, and instructions.
