RF Engineer (Hea Job/ 282)

Job Description: Senior RF System Engineer

Key Responsibilities

• Develop Tx/Rx signal chain architecture including LNA, driver amplifiers, mixers, filters and matching networks.
• Design RF front‑end covering wideband frequencies up to multi‑GHz.
• Develop clocking architecture (PLL, LO, low‑phase‑noise clocks) and deterministic latency using SYSREF. Define frequency planning, LO distribution, and clock synchronization across channels.
• Perform RF link budget, gain distribution, and noise analysis.
• Configure DDC/DUC channels for multi-channel radar processing.
• Interface RF converters with FPGA using JESD204B/C high-speed serial links.
• Support digital beamforming architecture with DSP and FPGA teams.
• Develop system architectures for radar, electronic warfare and phased‑array systems.
• Support PCB layout for RF and high‑speed digital interfaces including signal integrity review.
• Perform RF testing, characterization and debugging using laboratory test equipment.
• Collaborate with FPGA, DSP and system engineering teams for complete RF system integration.

RF Testing & Validation

• Perform RF testing using a spectrum analyzer, signal generator, network analyzer, and high-speed oscilloscopes.
• Perform RF validation, including Channel-to-channel phase error measurement, Channel gain variation analysis, Noise figure measurement, Spurious-free dynamic range (SFDR) validation, Linearity (IP3), Phase noise, and Intermodulation distortion (IMD) testing

Required Experience

• RF system design for radar or electronic warfare systems
• Familiarity with clock generation ICs and RF synthesizers ADI MxFE devices (AD9081 / AD9082 / AD9084)
• Experience with GSPS ADC/DAC and direct RF sampling architectures.
• Clock synchronization in multi-converter systems
• RF front-end design experience up to DC–18 GHz.
• Knowledge of JESD204B / JESD204C interfaces.
• Experience in phased array radar or EW systems.
• Experience integrating RF systems with FPGA platforms (Xilinx / Intel / Microsemi).
• Understanding of RF matching networks, filters, and amplifiers.
