Description

Join our Team About this opportunity: As a PA Developer, you will join the PA design team in the Radio Pacific Radio Design 1 department in Beijing, working in a diverse and collaborative environment with tens of colleagues who fully cooperate to deliver cutting-edge radio solutions. The team mainly focuses on new PA technology research and solution design for Ericsson radio products. In this role, you will apply strong RF/microwave expertise and hands-on PA hardware design skills to develop high-performance, energy-efficient PAs that strengthen our radio product competitiveness and innovation. What you will do: Contribute to new PA technology study and solution design for Ericsson radio products as part of the PA design team. Design and optimize PA hardware circuits, applying solid microwave and electromagnetic field knowledge and PA theory. Use RF simulation tools such as ADS, AWR, and HFSS to model, analyze, and refine PA performance. Plan and conduct PA-related lab measurements using radio test instruments including spectrum analyzers, network analyzers, signal generators, and power meters, and interpret results to guide design changes. Provide PA proposals including link budget, power budget, and line-up; evaluate key components and select appropriate solutions. Perform PA transistor internal design and related tasks to ensure optimal performance and reliability. Use CAD tools such as Mentor or Cadence to implement and maintain PA schematics and layouts. Support broader product development activities including requirement analysis, system/architecture/hardware design, integration, verification, tools design, and documentation support as needed. Continuously learn and research up-to-date PA and radio technologies, contributing to innovation and knowledge sharing across the team. The skills you bring: M.S. degree or above in Microwave engineering, wireless communication, RF/microwave electronics, or an equivalent major. More than 3 years’ working experience in PA hardware design for communication or radio products. Solid knowledge of microwave and electromagnetic field theory, with strong understanding of PA theory and techniques used in communication systems. Proven ability to provide PA proposals, including link budget, power budget, and line-up, and to evaluate and select key components for PA designs. Experience in PA transistor internal design and practical implementation. Familiarity with radio test instruments such as spectrum analyzers, network analyzers, signal generators, and power meters, and experience using them for PA validation. Proficiency with CAD tools (e.g. Mentor Graphics, Cadence) and RF simulation tools (ADS, AWR, HFSS) for schematic/layout and performance analysis. Strong ability to learn new techniques and willingness to research up-to-date technologies, combined with a collaborative and team-oriented mindset. Good communication skills and the ability to work closely with cross-functional product development teams (system, hardware, test, etc.).
