OVERVIEW & IMPACT:

At Samsung Semiconductor Inc, we are always working on innovating for the next generation wireless mobile platform architecture. As we're growing our business in the wireless mobile applications, we're looking for a talented RF system architect with strong technical background and hands-on experience in RF system engineering to join us to craft our next generation wireless mobile platform solution. You'll have the unique opportunity to define "best-in-class" RFFE and RFIC architecture, bring new RF concepts and features to the platform, and optimize overall platform RF performance, with emphasis on sub-6GHz and NR-U bands RF-modem system applications. We value your relevant industrial experience in cellular (LTE and 5G NR) and/or connectivity (WiFi, Bluetooth and etc.) applications. You will work closely with RFFE vendors, internal RFIC and Modem system teams to develop SOC and platform architecture, define key RFIC and RFFE KPIs, and RF-modem algorithm requirements for next generation wireless mobile platform solution. Come join us, bring your passion and dedication to innovate and deliver products which enrich people’s lives!

JOB RESPONSIBILITIES:

• Analyze next generation cellular FR1 RF-Modem system architecture using Excel, Matlab, Python, and SystemVue
• Support product architecture definition for next generation sub-6GHz,NR-U cellular and connectivity SOC
• Co-work with RFFE partner and RFIC design team to define SOC RF specifications and drive differentiation in the RF Front End sub-system definition
• Co-work with RF System algorithms and modem teams on FR1 SOC calibration requirements, RF impairments compensation techniques, Tx linearization (ET/APT_DPD), Rx self-interference cancellation, and Rx automatic gain control (AGC) optimization.
• Drive RF-modem system validation and commercialization at the platform level with RF SW and RF HW teams
• Drive engagement with key OEMs in providing RF systems architecture expertise to validate requirements and support phone set development with S.LSI next generation LTE/NR cellular chipset
