What‘s Hybrid microwave circuit board？

Hybrid microwave PCB is using a dissimilar materials with the intent of optimizing electrical performance and improving system reliability focused towards high-frequency RF applications. 

These designs include a combination of FR-4 material and PTFE laminates typically. It allows the designer to condense both RF functionality and RF functionality on the same PCB and reduce both the footprint of the device and the costs.

Manufacturing Innovation

By combining a low-loss material (such as PTFE or Rogers) with another core material (such as FR-4) in a single laminate. Hybrid Microwave PCBs can:

• Significantly reduce space and save costs

• Integrate RF and non-RF components on a single board

• Optimize signal integrity for complex applications
  

Hybrid RF PCB Laminate Construction Considerations

When manufacturing PCBs with different materials, expertise in laminate physical properties and equipment capabilities is critical. Due to varying CTE values of all material layers (e.g., FR4, PTFE, copper), each expands at a different rate during high-temperature processes like lamination. This causes major registration issues (from differential shrinkage/expansion) and potential delamination at copper-substrate interfaces. So, not all materials suit hybrid applications—some are unmanufacturable even if they meet performance requirements.

Collaborating with supplier early in the design process delivers the best results, as they know which materials pair optimally. For example, Rogers 5880 is an excellent RF material for high-reliability uses. Its key challenge is shrinkage after copper etching, so fabricators must understand this to compensate in their processes.

Applications

High-frequency Hybrid Microwave PCBs are widely used in wireless antennas, base station receiving antennas, power amplifiers, radar systems, navigation systems and other communication equipment.
