FY27 Intern - RF Systems & Cell Validation Engineering - 6 months, Cambridge

##

Company:

Qualcomm Technologies International Ltd

## Job Area:

Interns Group, Interns Group > Interim Intern

General Summary:

We are looking for a creative, hands-on and self-motivated intern to join our Cambridge RF Systems team for a summer placement.

The successful candidate will work on RF system analysis, system and cell validation and performance optimization for advanced wireless products, with particular focus on WLAN and Bluetooth radio systems. The project will provide exposure to the complete RF development process, from system-level modelling and performance analysis through to laboratory measurements and silicon bring-up/debug.

The internship may involve analysis of key RF performance metrics such as transmit power, EVM, spectral performance, receiver sensitivity, gain, noise, frequency accuracy, LO performance and RF impairments. MATLAB and/or Python will be used for data analysis, modelling and automation.

A significant part of the placement will involve practical RF measurements in our Cambridge RF laboratory using state-of-the-art RF test equipment. The intern will have the opportunity to compare measured silicon performance against system expectations, investigate performance limitations and contribute to the development of measurement and debug methodologies.

Skills / Experience

Essential:

• Good understanding of analogue/RF circuits and basic communication-system concepts.
• Familiarity with RF concepts such as gain, noise, modulation, frequency response and signal spectra.
• Experience with MATLAB, Python or a similar technical computing environment.
• Strong analytical and problem-solving skills.
• Interest in practical laboratory-based engineering.

Desirable but not essential:

• Knowledge of wireless communication systems such as WLAN, Bluetooth, cellular or similar technologies.
• Familiarity with concepts such as EVM, IQ imbalance, LO leakage, phase noise, receiver sensitivity and RF calibration.
• Experience using RF laboratory equipment such as spectrum analysers, signal generators, vector signal analysers or oscilloscopes.
• Experience with automated data analysis or measurement scripting.

Responsibilities

This is a summer placement of fixed duration. The successful candidate will work under the guidance of experienced RF Systems engineers and will contribute to an active wireless RF development project.

Typical activities may include:

• LO/TX/RX such as measuring TX Power, LO Phase Noise/Spurs or Receive NF and comparing against expected system behavior
• Performing system-level modelling and RF performance analysis.
• Developing Python or MATLAB scripts for measurement automation, data processing and visualization.
• Supporting debug, RF calibration, characterization and validation activities.
• Documenting measurement methods, results, conclusions and recommendations so that the work can be reused by the wider engineering team.

The placement will provide practical experience of RF system engineering and the development and validation of complex wireless products, while working alongside experienced RF, analogue, digital and validation engineers.

Education Requirements

Currently studying towards Master’s degree in Electrical Engineering, Electronic Engineering, Communications Engineering or a closely related discipline.

Students with particular interest in RF engineering, wireless communications, signal processing or RF measurement and validation are encouraged to apply.

*References to a particular number of years experience are for indicative purposes only. Applications from candidates with equivalent experience will be considered, provided that the candidate can demonstrate an ability to fulfill the principal duties of the role and possesses the required competencies.
