The technology
What is a high-frequency PCB?
A high-frequency PCB is built on a low-loss laminate instead of, or alongside, standard FR-4. Common material families are PTFE-based laminates (e.g. Rogers RT/duroid) and hydrocarbon-ceramic laminates (e.g. Rogers RO4000 series). What they share is a stable dielectric constant (Dk) across frequency and temperature, and a low dissipation factor (Df), so signals lose less energy and impedance stays predictable. At RF and microwave frequencies, and in fast digital links, those properties decide whether the circuit performs as simulated. Impedance control and the exact laminate choice are therefore central to the design.
Our network includes manufacturers experienced in Rogers, PTFE and other low-loss laminates, including hybrid stack-ups.
Applications
When to choose a high-frequency PCB
Choose a high-frequency laminate when signal loss or Dk stability on FR-4 would limit performance. Typical applications:
- RF front-ends, power amplifiers and filters.
- Antennas, including patch antennas and phased arrays.
- Radar, including automotive radar sensors.
- Satellite communication and microwave links.
- High-speed digital designs where loss and impedance consistency limit link performance.
- Test and measurement equipment that needs repeatable RF performance.
Design for manufacturing
High-frequency PCB design tips
- Specify the laminate by name and grade, or by Dk and Df targets at your operating frequency, so the manufacturer can quote the right material.
- Consider a hybrid stack-up, with low-loss material on the RF layers and FR-4 on the inner layers, to manage cost.
- Take copper roughness into account; rough copper increases conductor loss at high frequencies, so low-profile copper foils may be needed.
- Define tight impedance control with an impedance table and coupons, and agree the trace geometry with the manufacturer.
- Remember that PTFE-based materials need special drilling and hole preparation before plating, which not every manufacturer runs routinely.
- Choose the surface finish deliberately: the nickel in ENIG adds conductor loss at high frequencies, so immersion silver or other finishes are often chosen.
Our free DFM check and the manufacturer's own engineering review help catch issues like these before production.

Common questions
FAQ about high-frequency PCBs
What is Rogers material in a PCB?
Rogers material refers to high-frequency laminates made by Rogers Corporation, such as hydrocarbon-ceramic and PTFE-based materials. They offer a stable dielectric constant and low dissipation factor compared with FR-4, which reduces signal loss and keeps impedance predictable at RF and microwave frequencies. The name is often used loosely for low-loss laminates in general, so always specify the exact grade.
When do I need a high-frequency laminate instead of FR-4?
You need a high-frequency laminate when FR-4's loss and Dk variation would limit performance: typically in RF and microwave circuits, antennas, radar, and fast digital links over long traces. There is no single frequency threshold; it depends on trace length, loss budget and impedance tolerance. Simulate with the laminate's actual Dk and Df before deciding.
What is a hybrid stack-up?
A hybrid stack-up combines different laminates in one multilayer board, usually a low-loss high-frequency material on the outer RF layers and standard FR-4 on the inner layers. It reduces material cost while keeping RF performance where it matters. Hybrid builds require matching lamination processes and attention to differences in thermal expansion, so agree them with the manufacturer.
Can a manufacturer substitute an equivalent laminate?
Yes, if you allow it. Manufacturers sometimes propose an equivalent laminate with similar Dk and Df that they stock or process routinely. That can improve availability and cost, but even small differences can shift impedance and RF performance. State in your quote request whether equivalents are acceptable, and approve any substitution in writing before production.
