Design, simulate, and verify RFIC blocks to meet gain, noise figure, linearity, and power targets (e.g., low-noise amplifiers (LNAs), power amplifiers (PAs), RF mixers, voltage-controlled oscillators (VCOs), phase-locked loops (PLLs), and switches) using CMOS, SiGe, BiCMOS, or GaAs process technologies. Drive silicon bring-up and lab characterization using RF test equipment (vector network analyzer (VNA), spectrum analyzer, noise figure meter, and load-pull) to validate performance against specifications.
