Rogers Impedance Calculator
RO4350B | RO4003C | RT/duroid | RO3000
Calculate trace width and impedance for Rogers high-frequency PCB materials. Low-loss, stable Dk laminates for RF, microwave, and high-speed digital applications where FR4 isn't sufficient.

When to Use Rogers Materials
RF & Microwave
Antenna designs, filters, couplers, and power amplifiers may need RF laminates when the selected FR4 stackup cannot meet the loss and impedance requirements.
Automotive Radar
Automotive radar designs need material selection based on the operating frequency, loss budget, and environmental requirements. Verify the chosen grade with the supplier.
High-Speed Digital
Long high-speed traces where the selected FR4 stackup exceeds the signal-loss budget. Hybrid stackups with Rogers and FR4 are common.
Rogers vs FR4 Comparison
Rogers Advantages
Considerations
Rogers Design Guidelines
Impedance Calculation
- • Use manufacturer's Dk at your operating frequency
- • Check the selected product datasheet and Dk test method
- • Confirm model assumptions with your fabricator
- • Trace widths depend on the selected Dk and stackup geometry
Hybrid Stackups
- • Use Rogers for RF/high-speed layers only
- • FR4 for power/ground and low-speed signals
- • Reduces cost while maintaining performance
- • Work with fab on bonding and registration
Calculate Rogers Trace Dimensions
Use our impedance calculator with Dk from the selected product datasheet. Confirm the operating frequency, test method, and stackup before using the estimate.
Rogers FAQ
Which Rogers material should I use?
Compare the selected product datasheets against your operating frequency, loss budget, processing needs, and cost. Confirm the choice and stackup with your fabricator.
How much more does Rogers cost?
Cost depends on the laminate, stackup, quantity, and fabrication process. Request quotes for the specific design; a hybrid stackup may be an option to discuss with the fabricator.
Can any fab process Rogers?
No. Rogers requires special processing knowledge. Work with fabs experienced in high-frequency materials. Many prototype fabs don't offer it.
What Dk should I use in calculations?
See your laminate supplier datasheet for the selected product. Confirm which Dk value and test method suit the operating frequency and impedance model with your fabricator.
