PA Design Engineer

Job Description:
We are looking for an experienced PA Design Engineer to work on-site at the Dallas R&D Lab. You will design, simulate and test RF Power Amplifiers (including Doherty Client) for radio products, and support the design from concept through to release.

Key Responsibilities:

• Design RF power amplifiers, including Doherty PA architecture and matching networks.
• Run simulations and load-pull analysis for gain, output power, efficiency, linearity, stability and ruggedness.
• Create PA schematics, select components, and prepare the PA BOM using Nokia part numbers.
• Lead PA design reviews and prepare design documents and release packages.
• Bring up PA prototypes, take RF measurements and find root causes of defects.
• Support design verification across temperature and supply-voltage conditions.
• Work with PCB layout and verification teams, and support PA/DPD performance tuning.

Required Skills & Experience:

• Hands-on experience in RF PA architecture and circuit design (Doherty PA preferred).
• Strong knowledge of RF matching, load-pull and performance optimization.
• Experience simulating gain, efficiency, linearity, stability and ruggedness.
• Good understanding of DPD interaction with the PA.
• Experience in schematic design, design reviews and documentation.
• Skilled in prototype bring-up, RF lab measurements and troubleshooting.
• Experience with Mentor Graphics Xpedition schematic tools.
• Good communication and reporting skills.

Work Location & Travel:

• Dallas R&D Lab on-site presence required for lab and design work.
