When designing RF PCBs, selecting the right material is pivotal for achieving optimal board performance. The properties of the RF laminates directly impact signal integrity, thermal management, impedance uniformity, dimensional stability, and manufacturing efficiency. Highlights: When designing radio-frequency boards: Choose laminates with a low dielectric constant (<4) and low dissipation factor (<0.005). Select materials with similar CTEs to prevent warping and improve reliability. Opt for high thermal conductivity materials for effective heat dissipation. Use low-profile copper foils to reduce signal losses. In this article, you will learn how to choose the right dielectric material for your RF circuit boards. Watch…
