High-power RF and microwave systems—such as RF amplifiers, 5G base stations, radar modules, satellite communication units, and microwave transmitters—require PCBs that can maintain stable performance under intense thermal and electrical stress. Ordinary FR-4 boards simply cannot handle the dielectric loss, heat generation, tight impedance requirements, and frequency-dependent behavior seen above 1 GHz.

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.
Specify the exact frequency band, such as:
Higher frequencies require lower-loss materials and tighter tolerances.
Provide the intended impedance values such as:
This allows the PCB manufacturer to determine trace width, spacing, copper thickness, and dielectric thickness.
Thermal load affects stackup and material choice, especially for:
Manufacturers may include metal-backed substrates or copper coins if required.
List materials if known:
Or request material recommendations based on your frequency and power.
Specify:
High-power RF typically needs high-copper layers for heat dissipation.
Provide details on:
These influence manufacturability and RF performance.
RF connectors need stable surface performance:
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.

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.
Common failure causes include:
Choosing the right RF PCB manufacturer greatly reduces failure risk.
For heat-heavy RF circuits:
Proper impedance ensures:
FR-4 is not recommended above 3–6 GHz due to high dielectric loss. For microwave frequencies, PTFE or Rogers materials are necessary.
