Designing for Ultra-Linear RF

Vandana CC

Engineering Project Coordinator
Sierra Circuits

Building RF systems that deliver true ultra-linearity goes far beyond picking the right IC. It demands a thoughtful, system-level approach that considers every layer of your design, from PCB layout and material selection to power amplifier architecture.

In this webinar, Sierra Circuits will walk you through how to design RF systems that maintain clean signals while meeting the demands of modern high-frequency applications.

We’ll break down how your layout decisions directly impact signal integrity and linearity, why low-loss laminates matter, and how to manage conductor and dielectric losses without sacrificing performance. You’ll learn how to design low-impedance return paths, avoid ground loops, and keep your system stable even under thermal load. We’ll also cover decoupling strategies to reduce harmonic distortion and ensure your signals remain clean at high frequencies.

What you’ll learn:

• How PCB layout choices influence RF signal integrity and linearity
• Selecting low-loss laminates: Impact of Dk and Df over frequency
• Managing conductor and dielectric losses for signal fidelity
• Minimizing impedance discontinuities in high-frequency signal lines
• Designing low-impedance return paths and avoiding ground loops
• Heat dissipation techniques to maintain linearity under thermal load
• Decoupling capacitor placement strategies to suppress harmonic distortion
