Qualcomm is a company of inventors that unlocked 5G ushering in an age of rapid acceleration in connectivity and new possibilities that will transform industries, create jobs, and enrich lives. But this is just the beginning. It takes inventive minds with diverse skills, backgrounds, and cultures to transform 5Gs potential into world-changing technologies and products. This is the Invention Age and this is where you come in.
In this role you will be working on advanced front-end modules for cellular/wireless applications as part of the Qualcomm’s RF Front-End (RFFE) Department.
The position offers the opportunity to characterize, validate and verify the performance of RF Front-End Modules to ensure design success. The Characterization Design Engineer is also responsible for analyzing the performance of the product under development and provide design feedback to the team. The responsibility extends to innovating RF/Analog Characterization techniques for complex products. Qualcomm solutions include highly customized LNAs, PAs, FEMs, antenna tuner and multi-throw switches in standalone and module packages for 4G and 5G wireless cell phone and ultra-mobile devices. You will work in a fast-paced team environment and be required to work closely with RF IC design engineers to optimize a design by extensive data collecting, analyzing the data and co-designing the product based on RF system knowledge. Responsibilities: – Design and develop engineering evaluation test boards for RFFE products – Develop Characterization Test Plans to report the performance of RFFE products in a highly automated RF test set-up – Work with LNA test setup such as PNAX, PXA, network analyzers, noise figure measurement, sophisticated Tx system tools such ET/DPD, system alignment, transceiver co-optimization as well as antenna tuners to optimize the performance – Characterization Report includes all the parametric data from RFFE such as Rx path NF, noise circles, IP2/IM2, IP3/IM3, Gain modes, S-parameters of Rx path components, as well as Tx path PAE, Gain, ACLR, power sweep, Rx Band Noise, Spectrum Emission Mask, harmonics, s-par, x-par, Load-pull, Out-of-band rejection, frequency sweep, etc. – Collect and evaluate data to verify performance over temperature, voltage, and process corners – Summarize and create performance reports – Select, implement, and maintain test equipment necessary for RFFE product characterization. Work with IC design team to maintain, optimize, and release module setting for overall optimized product performances.
All Qualcomm employees are expected to actively support diversity on their teams, and in the Company.
