About The Position

Join us in advancing the country's digital agenda with 5G technology as a RF Power Amplifier Designer. You'll enhance our hardware products through requirement analysis, system and hardware design, integration, verification, simulations, tools design, and product documentation. We emphasize on Lean and Agile Product Development methodologies within cross-functional teams that prioritize continuous improvement, innovation, and knowledge sharing across domains.

Requirements

Minimum of 3 years of experience working directly in the development of radio products (RF systemization, RF hardware design, integration, or test).
Good understanding of RF electronics, RF system design and wireless systems theory and technology.
Good knowledge of 3GPP specifications, especially in Radio performance characteristics.
Knowledge of radio standards (2G, 3G,4G, GSM, WCDMA, LTE, NR, Wi-Fi, 5G)
Good knowledge of RF test instruments and verification process for PA design.
Knowledge of Load Pull simulations and measurements is important.
Material Physics knowledge on PA Semiconductor device level is important.
Experience of development and analysis of simulations, knowledge of simulation environments like ADS, AWR, HFSS and CST.
Python and MATLAB based scripting experience.
Wide Band and high-Power GaN PA knowledge
PA supplier knowledge and technology trends.

Responsibilities

Design and simulation of PA board circuit level designs.
Deep understanding of component selection and characterization for PA designs.
Experience with analysis and optimization of PA and RF circuits in general.
Good experience of lab testing using RF test equipment’s.
Assist in troubleshooting and solving product related issues.
Experience of working with Link budgets
Perform open and closed loop testing during the project development life cycle.
Some understanding of TX low power and Transmit observation receiver would be required.
Working with a wider design community to understand system architecture, link-budgets for transmit chain and defining amplifier solutions that would fulfil all requirements (i.e., performance, form-factor, cost, manufacturability etc.) for a timely & successful product delivery.
Designing & developing high-power amplifiers modules (10W to 200W) in the 400 MHz to 5000 MHz frequency range and will support their higher-level integration into radio with digital pre-distortion techniques to meet regulatory & internal requirements.
Modeling and characterizing linear/non-linear circuit elements used in high-power RF power amplifier modules.
Using advanced CAD/Simulation tools for modelling, analysis and to generate layout & schematics for power amplifier module.
Utilizing your analytical skills to troubleshoot & solve (design/manufacturability) issues at both, power amplifier module-level, and upon its integration at the radio system-level.
