Job description

RF Design Consultant | Outside IR35 | £60-70p/h

My client requires an experienced RF Design Engineer to provide expert-level hardware development and integration support for our next generation of high-reliability wireless terminals. The consultant will be responsible for the end-to-end design, simulation, and hardware-level optimisation of critical RF subsystems.

Scope of Work & Deliverables:

• Complete component-level schematic design and PCB layout supervision for high-power RF chains, specifically focusing on Power Amplifiers (PA), Low Noise Amplifiers (LNA), and Frequency Generation circuitry.
• Perform detailed circuit and electromagnetic simulations using ADS or CST to predict performance and ensure first-pass success of matching networks and filter designs.
• Deliver optimised hardware solutions operating across the 700MHz to 6GHz range, ensuring full compatibility with 5G/LTE/4G and WiFi standards.

Required Technical Expertise:

• Deep expertise in discrete RF hardware design (Transmitters, Receivers, and PAs).
• In-depth understanding of 3GPP (5G/LTE) and 802.11 (WiFi) physical layer requirements.
• Use of Spectrum Analysers, Network Analysers, and high-speed oscilloscopes.
• Must be eligible for UK Security Clearance.
• Duration: Initial 6 months, potential for extension
• Location: Primarily on-site (Cambridge) for hardware lab access; hybrid for design/simulation phases.
• Hours:37.5 hours per week with a flexible approach to meet project milestones
