What Should You Provide for High-Power RF PCBs?
When ordering high-power RF microwave PCBs, your manufacturer needs precise engineering data to ensure correct impedance, dielectric performance, and thermal stability. Below is a complete checklist.
1. Operating Frequency Range
Specify the exact frequency band, such as:
- 1–6 GHz (RF)
- 10–30 GHz (Microwave)
- 24–77 GHz (mmWave)
Higher frequencies require lower-loss materials and tighter tolerances.
2. Target Impedance & Tolerance
Provide the intended impedance values such as:
- 50Ω microstrip
- 75Ω signal lines
- Differential RF pairs
This allows the PCB manufacturer to determine trace width, spacing, copper thickness, and dielectric thickness.
3. Expected Power Handling / Heat Load
Thermal load affects stackup and material choice, especially for:
- RF amplifiers
- High-power transmitters
- Power combiners/splitters
Manufacturers may include metal-backed substrates or copper coins if required.
4. Material Preferences
List materials if known:
- Rogers 4350B, 4003C, 5880, 3006
- Taconic TLX, TLY, RF-35
- Isola Astra / I-Tera HT / PTFE laminates
Or request material recommendations based on your frequency and power.
5. Stackup Requirements
Specify:
- Number of layers
- Hybrid stackup (PTFE + FR-4)
- Dielectric thickness
- Copper weight (e.g., 1oz, 2oz, 3oz+)
High-power RF typically needs high-copper layers for heat dissipation.
6. RF-sensitive Structure Information
Provide details on:
- RF cavities
- Via fences / Ground vias
- Via-in-pad for RF chips
- Microstrip or stripline routing
These influence manufacturability and RF performance.
7. Connector Type & Finish
RF connectors need stable surface performance:
- ENIG
- ENEPIG
- Hard gold
Let the manufacturer know if you’re using SMA, MMCX, SMP, or edge-launch connectors. Please remember, the more detailed information you provided, the fast you get your prototype.

FAQs
1. What is an RF microwave PCB?
An RF microwave PCB is a printed circuit board designed to operate at high frequencies (1–100+ GHz). It uses low-loss materials such as Rogers or PTFE to maintain stable impedance and minimize signal attenuation.
2. What causes high-power RF PCBs to fail?
Common failure causes include:
- Excessive heat
- Poor thermal design
- Incorrect stackup selection
- Impedance mismatch
- Delamination from improper lamination of PTFE materials
Choosing the right RF PCB manufacturer greatly reduces failure risk.
3. What is the recommended copper thickness for high-power microwave PCBs?
For heat-heavy RF circuits:
- 2 oz or 3 oz copper is common
- 4–6 oz for very high-power amplifiers
4. Why is controlled impedance so important in RF PCB design?
Proper impedance ensures:
- Lower insertion loss
- Minimal signal reflection
- Stable RF phase and amplitude
- Accurate high-frequency performance
5. Can I use FR-4 for microwave PCBs?
FR-4 is not recommended above 3–6 GHz due to high dielectric loss. For microwave frequencies, PTFE or Rogers materials are necessary.
