Senior RF Design Engineer

Senior RF Design Engineer The Role: Our client is seeking an experienced Senior RF Design Engineer to take a leading role in the design and development of RF components and subsystems for their future product line. You will leverage your expertise in discrete RF design to create high-performance solutions in the 100-1,000 MHz frequency range, focusing on filters, amplifiers, oscillators, mixers, and power amplifiers. Responsibilities for the role of Senior RF Design Engineer will include:

• Lead the design, simulation, and optimization of discrete RF components such as filters , low noise amplifiers (LNAs) , mixers , voltage-controlled oscillators (VCOs) , phase-locked loops (PLLs) , and RF power amplifiers (up to 5W) in the 100-1,000 MHz frequency range.
• Apply S-parameter design techniques and use RF circuit simulation software (e.g., Keysight ADS, Microwave Office, or similar tools) to model, design, and validate RF circuits.
• Contribute to the design and testing of component-level analogue circuits from DC to 10 MHz , with a focus on feedback circuits and their integration with RF subsystems.
• Work closely with cross-functional teams (hardware, software, and mechanical engineers) to integrate RF components into the final product.
• Perform detailed testing, debugging, and troubleshooting of RF and analogue circuits to ensure performance meets product specifications.

• At least 10 years of experience in discrete RF design.
• Strong expertise in the design and development of key RF components, including filters , low noise amplifiers (LNAs) , mixers , voltage-controlled oscillators (VCOs) , phase-locked loops (PLLs) , and RF power amplifiers .
• Proficient in RF circuit simulation (e.g., using Keysight ADS , Microwave Office , or equivalent software) and the use of S-parameters for design validation.
• Strong understanding of RF testing equipment such as network analyzers , spectrum analyzers , and signal generators .
• Excellent problem-solving skills, with a strong ability to troubleshoot complex RF and analogue designs.
• Strong communication skills with the ability to collaborate effectively in a multidisciplinary team.
