RF & High-Frequency PCB
Rogers and PTFE laminates with controlled impedance for RF, microwave and high-speed designs.
Material that behaves at frequency.
At radio and microwave frequencies the laminate becomes part of the circuit. Standard FR-4 has a dielectric constant that varies with frequency and from batch to batch, and it absorbs more of the signal as frequency rises. High-frequency laminates hold a stable dielectric constant and low loss, so filters, antennas and transmission lines behave as designed.
We supply boards on the Rogers RO4000 and RO3000 series, RT/duroid and other PTFE and ceramic-filled laminates, and on low-loss materials such as Panasonic Megtron 6 for high-speed digital designs. Tell us the laminate you designed for. If you are open to equivalents, we will say what is available.
When to choose it
- Antennas, filters, couplers and other circuits where the board geometry sets the electrical behaviour.
- Radar, radio links and telecom equipment at microwave frequencies.
- High-speed digital links where the loss in FR-4 is too high.
- Designs that need tight, repeatable impedance.

Design notes
- Name the exact laminate and thickness in the fabrication data. The manufacturer's name alone is not enough.
- State the impedance targets and which traces they apply to.
- Point out critical etched features, such as filter gaps or antenna dimensions, so they can be checked before production.
What we need to quote
Your production files (Gerber and drill data) with a fabrication drawing or readme that states board thickness, surface finish and copper weights.
For RF boards, include the laminate type and thickness for each layer, and the impedance requirements.
For assembly on the same order, add the BOM, assembly drawing and pick-and-place file.

Certificates and documentation
ISO 9001, ISO 14001 and ISO 45001 certificates from our manufacturing partner, together with RoHS and REACH declarations, are available on request.
