Kruthika MS - RF Test Engineer - Bharat Electronics Ltd,(BEL) Ministry of Defence

Summary

I'm an RF engineer with 2 years' experience at Bharat Electronics Limited, Bengaluru, focused on defence electronics. I enjoy hands-on testing and troubleshooting of L‑Band and HF power amplifiers, using signal generators, spectrum/signal analyzers and VNAs to characterize performance and trace faults down to the PCB level. I take pride in delivering accurate test reports, diagnosing issues like low gain, high VSWR and thermal faults, and maintaining strict defence quality and ESD practices. I'm eager to apply my practical lab skills and collaborative problem-solving approach to challenging RF test and development roles.

L-Band and HF Power Amplifier Testing in Software Defined Radio - Tactical Communication
Executed functional and performance testing on L-Band and HF Power Amplifiers for defence communication and radar systems, ensuring compliance with stringent specifications.
Measured key parameters including output power, power gain (S21), return loss (S11), harmonics, and spurious emissions against strict defence specifications.
Conducted signal tracing through pre-driver, driver, and high-power MOSFET stages to evaluate RF path integrity.
Diagnosed and resolved RF failures, enhancing module reliability by addressing issues like low power gain, excessive VSWR, and thermal inconsistencies.
Analyzed output spectrum using Signal/Spectrum Analyzers to monitor harmonics, power levels, and unwanted spurious signals.
Configured and calibrated Vector Network Analyzers (VNA) to measure S-parameters, return loss, and insertion loss.
Utilized Signal Generators for continuous wave (CW) and modulated signal injection to verify receiver/amplifier gain stages.
Assisted in module-level assembly and RF subsystem integration.
Maintained accurate test reports, troubleshooting logs, and calibration records in accordance with defence quality assurance standards.
