Senior PA Design Engineer

Job Title

Senior PA Design Engineer

Role Summary

Design and develop high-efficiency, high-linearity cellular power amplifiers (PAs) and RF front-end modules for 5G NR and 6G smartphones. The role spans PA architecture definition through die integration, simulation, measurement, and driving designs into high-volume manufacturing.

Collaborate with filter, packaging and systems teams to optimize module-level performance and present results to internal and external stakeholders.

Experience Level

Senior / Professional; typically requires 3+ years of industry experience.

Responsibilities

Key responsibilities include:

• Design and develop PAs targeting high linearity, wide modulation bandwidth, high power and high efficiency using GaAs HBT technologies.
• Lead integration of PA dies into multi-chip modules (MCM), optimizing for size, cost and thermal performance.
• Perform 3D electromagnetic simulations (HFSS) and circuit-level simulations (ADS) and ensure model-to-measurement correlation.
• Develop and execute RF measurements and characterization to validate designs.
• Collaborate with SAW/BAW filter, packaging and systems engineers to optimize top-level module performance.
• Document and present technical results to internal teams and external customers; drive designs to manufacturable solutions.

Requirements

Core technical and professional requirements.

• Must-have: Strong understanding of RF fundamentals (S-parameters, impedance matching, stability, linearity).
• Extensive experience in RF circuit design and simulation using Keysight ADS, HFSS, and Cadence.
• Proven experience in RF measurements and characterization.
• Ability to work independently in a fast-paced environment and strong technical communication/presentation skills.

Nice-to-have:

• Experience with GaAs HBT PA design, MCM integration, and thermal/size/cost optimization.

Education Requirements

Minimum of an MSEE with at least 3 years of industry experience, or a Ph.D. degree.
