RF PCB Design
High-frequency PCB engineering for controlled impedance, low insertion loss and predictable signal behavior—from stackup planning and RF layout through DFM review and prototype validation.
- Transmission-line and impedance control
- Low-loss materials and stackup engineering
- Grounding, shielding and EMI risk reduction
RF layouts built around frequency, materials and real fabrication limits
RF PCB performance depends on far more than routing a trace to a nominal impedance. The laminate system, copper profile, dielectric thickness, reference planes, connector launches, component footprints and enclosure geometry all influence the final electrical behavior.
Our design workflow brings those constraints together early. We define practical transmission-line structures, protect return-current paths, manage coupling between RF, digital and power regions, and keep the layout compatible with the selected fabricator’s process capability.
Design priorities we review
- Operating frequency, bandwidth and loss budget
- 50Ω / differential impedance targets and tolerances
- Microstrip, stripline and grounded coplanar geometry
- RF grounding, via fences, shielding and isolation
- Launches, transitions, test access and DFM constraints

Representative RF projects engineered for signal integrity and production
Each RF layout begins with operating frequency, impedance targets, insertion-loss limits and enclosure constraints—then develops the stackup, transmission-line geometry, grounding and validation plan around those requirements.
5G RF Front-End Module
A compact RF front-end layout combining controlled-impedance signal paths, filtering and sensitive active devices within a restricted mechanical outline.
Design challenge
Reduce discontinuities and coupling while preserving short, predictable RF paths between the transceiver, filters and antenna interface.
Engineering approach
50Ω transmission-line control, grounded coplanar routing, via-fence planning, RF/DC zoning and component-transition optimization.
Microwave Control & Sensor Board
A mixed-signal microwave controller requiring stable RF performance alongside digital control, clock and power-management circuitry.
Design challenge
Prevent digital return currents and switching noise from degrading low-level RF paths across multiple functional zones.
Engineering approach
Low-loss laminate selection, microstrip/stripline transition control, return-path continuity, isolation zoning and stackup review.
High-Frequency Prototype Validation
An RF prototype prepared for repeatable bench evaluation, connector launch tuning and correlation between design assumptions and measured behavior.
Design challenge
Create measurement access without introducing unnecessary stubs, launch discontinuities or unstable grounding at the test interface.
Engineering approach
SMA launch optimization, calibration-aware test points, controlled reference planes and review of S-parameter and impedance results.
These examples illustrate representative project types and engineering approaches. Details are adapted to protect customer confidentiality.
