Career Opportunities: PA linearization and Modelling Developer (773832)
Join our Team
At this time, Ericsson Canada Inc. does not provide immigration assistance/sponsorship now or in the future for this position.
About this opportunity
This position focuses on contributing to the development of 5G technology as a Power Amplifier linearization and modeling developer. Responsibilities include requirement analysis, system and hardware design, integration, verification, simulations, tool design, and product documentation. The role involves developing sub-system algorithms and integrating machine learning capabilities, with tasks related to signal processing, reduction of signal distortion in Power Amplifiers, and linearizing the downlink chain within Ericsson Radios. Additional responsibilities include collaboration with the PA hardware, DPD/Algorithm, transmitter design, transmit observation receiver, and integration teams at Ericsson.
What you will do
- Select and characterize components for PA designs, analyze and optimize PA/RF circuits, and work with RF link budgets.
- Perform open and closed downlink loop testing during development.
- Basic understanding of TX low power and transmit observation receiver is required.
- Collaborate with design teams on system architecture and link budgets, defining Power Amplifier solutions that balance performance, cost, and manufacturability for timely product delivery.
- Design and develop high-power, wideband PA modules (1W–100W, 600MHz–6000MHz) and integrate them into radio systems with DPD linearization.
- Model and characterize linear/non-linear circuit elements in RF amplifier modules.
- Develop and optimize DSP and ASIC/FPGA algorithms for DPD, CFR, and digital filter design.
The skills you bring
- Candidates should have at least 3-5 years’ experience in developing algorithms for ASICs and FPGAs, along with intermediate knowledge of RF systems and PA hardware design, including TRX Downlink chain and within integration of radio HW and SW products.
- Experience or understanding of data communication theory, integrated circuits design and operation, electronics, RF system design, and wireless and mobile communication systems technology.
- Familiarity with 3GPP specifications, particularly radio performance characteristics.
- Knowledge of radio standards including 2G, 3G, 4G, GSM, WCDMA, LTE, NR, Wi-Fi, and 5G.
- Understanding of RF test instruments and verification processes for PA design.
- Background in material device physics related to wide band and high-power LDMOS, GaN, and GaAs PAs.
- Experience with Python and MATLAB scripting and automation.
- Theoretical and practical knowledge of ASIC, FPGA, and DSP.
- Ability to work innovatively and collaboratively and adapt to new challenges.
