Join our Team

About the opportunity
You will join the PA Design team in PEU Radio Pacific Chengdu, responsible for the full power amplifier (PA) lifecycle in our radio products – from design and simulation to verification, optimization and support in volume production. The team focuses on delivering high-quality, high-efficiency PA solutions on time, with a strong culture of ownership, execution excellence and cross-functional collaboration.

What you will do

• Design, simulate and optimize RF/microwave PA circuits for radio products from concept to maintenance.
• Perform PA simulations using tools such as ADS, AWR and HFSS, translating system/product requirements into implementable PA designs.
• Plan and execute PA lab measurements, characterize key performance parameters and tune designs to meet efficiency, linearity and robustness targets.
• Independently debug PA performance issues from simulation to HW bring-up, using structured root-cause analysis and clear documentation.
• Collaborate with system, RF, HW, test and manufacturing engineers to secure design-to-test closure and robust, volume-ready implementations.
• Contribute to continuous improvement of PA architectures, line-ups and design methods to support high-performance, energy-efficient radio solutions.
• Share knowledge and best practices within the team and participate in reviews and technical discussions, clearly explaining design decisions and trade-offs.

The skills you bring:

• Master’s degree or above in Electronics, Electrical Engineering, RF/Microwave Engineering or related field.
• Solid understanding of RF/microwave fundamentals.
• Hands-on experience in RF or PA design (schematic and layout), with exposure to RF power devices and front-end modules.
• Proficiency with RF/EM simulation tools (e.g. ADS, AWR, HFSS) and ability to correlate simulation and measurement results.
• Experience in PA lab validation and measurement (e.g. S-parameters, gain, P1dB, ACLR, EVM, efficiency), including tuning and troubleshooting to meet targets.
• Proven independent design/debug capability, strong problem-solving skills and ownership from initial design through test and release.
• RF-related work experience (e.g. PA, RF front-end, radio HW or similar domains).
• Good communication skills, collaborative mindset and willingness to continuously learn.
