Design and develop RF and analog circuits such as LNAs, mixers, power amplifiers, VCOs, PLLs, and ADC/DACs. Perform system-level analysis to optimize RF performance parameters like gain, noise figure, linearity, and phase noise. Conduct circuit simulations using tools like Cadence Spectre, ADS, HFSS, Momentum, and EMX. Collaborate with layout engineers to ensure optimal floorplanning, parasitic extraction, and RF routing. Conduct post-layout verification and EM simulations for high-frequency designs. Participate in lab validation and characterization of fabricated ICs, debugging issues, and improving performance. Work closely with system architects and digital design teams for mixed-signal integration. Support product engineering and test development for production ramp-up. Qualifications: 2 to 5 years of experience in RF/analog IC design. Strong understanding of RF circuit design principles, including impedance matching, S-parameters, and nonlinearity analysis. Hands-on experience with Cadence Virtuoso, Spectre RF, ADS, HFSS, or similar EDA tools. Knowledge of CMOS/BiCMOS process technologies and parasitic-aware design methodologies. Experience in EM simulation and modeling of on-chip passives (inductors, transmission lines, baluns). Familiarity with RF lab equipment (network analyzers, spectrum analyzers, signal generators). Strong problem-solving skills and ability to work in a fast-paced startup environment. Excellent communication and teamwork skills.
