Cohu is seeking an Electrical Engineer with experience in RF and SI theory to design, optimize, analyze and support hardware for semiconductor test interfaces. The primary responsibility of this position is to design and develop test interface solutions for semiconductor manufacturers used in the cmWave and mmWave markets including 5G, satellite communication, WiGig, and automotive radar. This position requires knowledge and use of 3D electromagnetic, 2D planar, and circuit level simulation for the modeling of compliant interconnects antennas, PCB layouts, and waveguides. The position also requires the knowledge and use of a Vector Network Analyzer for characterization of interface hardware. Both mechanical and electrical aptitude is required as well as solid communication and organization skills and the ability to work on a cross-functional team. Project management responsibilities include maintaining timelines and milestones of simulation and measurement activities, alignment with mechanical engineering teams and customer communication of RF simulation and characterization results.

Essential Duties and Responsibilities:

·        Research and apply theory of signal integrity/Power Delivery/antenna concepts related to PCBs, test sockets and other interconnect technology.

·        Design and integrate antennas/waveguide/RF Chokes/filters/couplers into interface hardware

·        Provide design recommendations for next-generation products that consider both electrical and mechanical performance tradeoffs for high volume semiconductor test environments.

·        Provide technical support to customers for RF test interface applications

·        Provide PCB, test socket, test probe design recommendations to Sales/Engineering/Customers

·        Review datasheets and device specifications and match interface hardware with RF applications

·        Generate RF test reports and presentations for new interface products

·        Present technical material to customers and at trade shows via powerpoint presentations

·        Limited travel required for onsite technical discussions, installations and trade shows.

 

 

Qualifications:

Education and/or Experience:

·        Bachelor's degree in electrical engineering (master’s preferred)

·        Understanding of transmission line theory

·        Simulation using 3D electromagnetic and circuit level simulation tools In depth knowledge of s-parameters and Vector network analysis into the mmWave frequency range.

·        Understanding of calibration procedures and theory of VNA hardware

·        Experience applying RF theory to mechanical design

·        Experience with mmWave theory and concepts

·        Knowledge of antenna theory and application to test interfaces

·        Use of mmWave products including waveguides, horns and patch antennas

·        Proven experience project management and undertaking a project from concept to end product

·        Familiar with Microsoft Office products including word, excel, powerpoint, and project

·        Strong verbal and written communications skills; ability to communicate effectively with both domestic and foreign colleagues/vendors
