Mobile Solutions EM / Filter Design - Principal Electrical Engineer

Job Description

If you are a motivated RF designer with skills and passion for designing complex multi-chip modules (MCM) that will be used in most cellphones sold today, the filter team if the Mobile Solutions Business (MSB) is looking for you!

As part of the filter design team, you will work on complex RF modules to integrate multiple dice from a variety of technologies to deliver best-in-class performance.  You will be designing and meticulously analyzing RF circuits such as impedance-matching networks, couplers, filter and embedded passives. 

The candidate is expected is expected to explore, devise and prototype a variety of RF circuits in order to enhance the competitive position of MSB.  The work involves close interaction with product teams to devise solutions that meet or exceed customer requirements.  The successful candidate will possess a deep understanding of electromagnetic theory and RF Circuits, and preferably has worked on design of either LNA, PA, or RF switches. The successful candidate will be responsible for EM analysis of active and passive RF front-end circuits.  Work experience with integrated RF front-end products is highly desired. The ideal candidate is adept in interfacing multiple RF components by devising proper routing, designing low loss impedance matching networks, conceive effective isolation and shielding techniques and subsequently analyze the entire module using advanced EM simulation tools. 

Key Responsibilities

Integration of filters with other constituents of an RF front end module to deliver the highest possible performance 
Designing embedded antenna multiplexer to support multi-band operations
EM analysis of RF assemblies using HFSS
Design acoustic wave filters for integration into RF modules, while meeting demanding schedules, best in class performance, and critical size and cost requirements
Follow Skyworks best engineering practices to ensure reliability, sustainability, and delivery of a high production yield
Drive new architectures and ideas to continuously improve filter and module performance to maintain a competitive edge for Skyworks products
Conduct design reviews and present quantitative data to demonstrate compliance to internal or customer specifications based on simulation and measured results
Work closely with module and systems teams to set appropriate goals for filter performance criteria
Interact with technology and fabrication teams to ensure continuous performance improvements and to steer BU roadmaps
Drive design methodologies to improve accuracy, efficiency, and first-pass success
Lead module co-design efforts, working directly with PA, LNA, switch, MCM, and other teams for a holistic approach to performance optimization
