The wireless RFIC team at Apple is responsible for architecting, designing, and validating radio transceivers that are integrated into complex wireless System on Chips (SoCs). These transceivers are crucial for powering wireless connectivity solutions in Apple wearable products, allowing for the smallest form factor while maintaining the lowest power consumption. As a member of this dynamic team, you will engage in innovative development in transceiver design, collaborating closely with systems and product teams at Apple. In this role, you will be part of an RFIC design team where your primary responsibilities will include testing, debugging, and measuring RF System on Chip (SoC) Intellectual Property (IP). You will run bench tests and debug various components such as transmitters, receivers, Phase-Locked Loops (PLLs), power amplifiers, Analog-to-Digital Converters (ADC), Digital-to-Analog Converters (DAC), crystal oscillators, and Power Management Units (PMUs). Additionally, you will address chip-level or board-level desense and Electromagnetic Interference (EMI) issues, write scripts to automate measurements, and perform RF system characterization by measuring parameters like Error Vector Magnitude (EVM), spectral mask, phase noise, and sensitivity. Your role will also involve designing external matching networks to optimize the transmission and reception performance of the radio, generating RF design, verification, and test reports, and collaborating with RF systems and integration teams on RF board layout, test interface methodology, programming sequences, and RF calibration programming. Synchronizing radio register settings between simulation and test environments will also be a key part of your responsibilities.
