RF and Microwave PCB Services
RF and microwave PCB performance depends on precise stack-up design, material selection, and impedance control. As operating frequencies increase, dielectric stability, conductor loss, and transmission line geometry become critical to signal integrity and predictable RF performance.
AdvancedPCB manufactures RF and microwave PCBs for applications including radar, phased arrays, satellite communications, and 5G infrastructure. From quick-turn prototypes to production builds, our processes are optimized for low insertion loss, controlled impedance, and repeatable high-frequency performance.
What Is an RF PCB?
An RF PCB is a printed circuit board specifically designed to carry high-frequency signals with minimal loss, reflection, or distortion. Unlike standard digital PCBs, RF and microwave designs require tighter control over dielectric properties, copper roughness, transmission line geometry, and stack-up architecture.
Key RF PCB requirements include:
- Controlled impedance structures
- Stable dielectric constant (Dk)
- Low dissipation factor (Df)
- Low conductor and dielectric loss
- Precise layer-to-layer registration
- Consistent material performance across frequency and temperature ranges
These factors directly impact insertion loss, phase stability, bandwidth, and overall RF system performance.
RF & Microwave Laminate Options
Material selection is one of the most important variables in RF PCB performance. AdvancedPCB supports a broad range of low-loss and high-frequency laminate systems for microwave and RF applications.
Supported material families include:
- Rogers RT/duroid laminates
- Rogers 4000 series materials
- Taconic RF materials
- PTFE-based laminates
- Hydrocarbon ceramic-filled materials
- Low-loss epoxy systems
| Material | Material Type | Typical DK | Typical Df | Common Applications |
|---|---|---|---|---|
| Rogers 4350B | Hydrocarbon/Ceramic | 3.66 | 0.0037 | RF modules, antennas |
| Rogers 4003C | Hydrocarbon/Ceramic | 3.55 | 0.0027 | Microwave circuits |
| RT/duroid 5880 | PTFE/Glass | 2.2 | 0.0009 | Radar and phased arrays |
| Taconic TLX | PTFE/Glass | 2.55 | 0.0012 | High-frequency RF designs |
| IS620i | Modified Epoxy | 3.58 | 0.0059 | High-speed digital/RF hybrids |
Low-profile and very-low-profile (VLP/HVLP) copper foils are often paired with these laminates to reduce conductor loss at higher frequencies.

Controlled Impedance and RF Stack-Up Design
RF stack-up architecture directly impacts insertion loss, impedance consistency, and phase stability.
AdvancedPCB works with engineers to optimize:
- Microstrip and stripline structures
- Grounded coplanar waveguide routing
- Differential pair routing
- Via transition design
- Copper foil selection and roughness
- Dielectric thickness consistency
Mixed-material RF stack-ups often combine PTFE RF layers with FR-4 or low-loss digital sections to balance electrical performance, manufacturability, and cost. These hybrid constructions require careful management of bonding compatibility, thermal expansion, and dielectric spacing during lamination.
Early stack-up collaboration helps reduce redesign cycles and improve first-pass success.
RF PCB Manufacturing Processes
High-frequency PCB manufacturing requires tighter process control than standard PCB fabrication.
AdvancedPCB uses process controls designed to support:
- Precise etch compensation for impedance accuracy
- Laser drilling for HDI and microvia structures
- Controlled via fill and planarization
- Low-contamination processing for RF laminates
- Dedicated PTFE bake and handling procedures
- Stable dielectric spacing across multilayer constructions
Copper roughness is carefully managed to reduce conductor loss and maintain repeatable RF performance.
Design for Manufacturability: RF PCB Guidelines
