RF Design Engineer (m/f/d)

Would you like to be part of Apple's fast-growing RF wireless design team in Munich? We are responsible for all aspects of wireless silicon development with a particular emphasis on highly integrated, power efficient designs and advanced semiconductor technologies that enable an outstanding user experience. IC design engineers work on circuit and system solutions for sophisticated wireless chips.

This is a highly visible role in a fast growing silicon design group where you'll have the opportunity to make a critical impact on getting innovative consumer products to a global customer base quickly!

Description
As a RF Design Engineer at Apple, you will use your vast background in circuit design and provide PLL design solutions for wireless chips. You will collaborate with platform architects, system group, and digital design group to define the requirements for a PLL lineup based on the product requirements. You will also work with the Apple technology team and silicon foundries on process evaluation/selection for the target device. Design tasks include various analog biasing blocks, oscillators, frequency dividers and local oscillator chains. You will work with system engineering, layout, and chip integration teams to integrate the IP's and verify the top-level functionality and performance. You also will work with RF test engineers to bring up, characterize and optimize new silicon.

Preferred Qualifications
A proven track record in RF, and analog integrated circuit design, with experience in wireless PLL circuit architectures in CMOS technologies.
Deep understanding in PLL system specifications and the ability to work with system architects to translate system requirements into circuit requirements at IC block level.
Knowledge in fundamental RF theories and concepts, such as innovative PLL concepts and their trade-offs in key performance parameters (KPI's), area and power efficiency.
The ability to optimize the overall PLL system including EVM, blocker requirements and crosstalk mitigations.
Deep technical knowledge in analysis, design, and implementation of RF wireless low-noise, broadband and power efficient PLLs, as well as frequency converting blocks.
Extensive experience in simulation of RF analog key building blocks, such as oscillators, frequency dividers, phase detectors and local oscillator signal distribution chains
Solid experience in optimization of RF circuit design impairments by means of highly sophisticated methods of trimming and calibration
Experience in RF cross talk analysis, understanding the critical RF cross talk building laws and the according aggressor and victim analysis, translation of RF system KPI's into IC block level isolation requirements
Understanding of RF device modelling, insights into packaging effects, integrated coils, supply isolations, high frequency ESD structures, and circuit layout for optimum performance.
Hands-on experience in high frequency silicon characterization and debugging on chip as well as on system level.
