Sr. RFIC Design Engineer , Amazon Leo

Key job responsibilities

Collaborate with communications systems, digital design, and chip implementation teams to specify and implement transceivers and RFIC front-end models which will delight future Kuiper customers.

Lead implementation of area/power-efficient RFIC chips with multiple transceiver chains with integrated PLLs from concept to production.

Work closely with packaging/HW/EE/FW teams to ensure seamless system integration providing best value for Kuiper customers.

Collaborate with the digital design team to define analog/digital boundary requirements for circuit calibration, clock generation, and timing.

Explore architectures for mm-wave and RF circuits like VCOs, mixers, phase shifters, LNAs, PAs, LO distribution, frequency multipliers and dividers, and envelope/power detectors, and make detailed presentations on power/area/performance trade-offs.

Design and simulate on-chip inductors, baluns, and power combiners in tools such as EMX or HFSS.

Perform circuit layout, RLC extraction, and run extracted simulation across various corners to make sure designs are robust and can be taken to volume production.

Specify bench and production test plans for your designs.

Basic Qualifications

Preferred Qualifications

• Master's degree or Ph.D. degree in Electrical Engineering or related field
• RF transceiver architecture / design for beamforming systems (including zero-IF transceivers, low-IF transceivers, polar transmitters, and RF/LO/Baseband phase shifting).
• Experience leading integrated RF transceiver chipsets containing LNAs, PAs, ADCs, DACs, baseband filters, mixers, etc.
• Millimeter-wave circuit design and layout in FinFET, SOI, BiCMOS, and Bulk CMOS technologies.
• Analog circuit design fundamentals, such as Opamps, precision biasing, and LDOs. Electromagnetics of passive devices and device physics of leading edge silicon and III-V devices.
• Mixed-signal design and verification techniques.
• Hands on experience with RF test equipment such as network analyzers, spectrum analyzers, oscilloscopes, and probe-stations.
• Strong written and verbal skills.
