Hybrid PCBs are more of a construction method than an actual material type, as it involves layering various microwave materials such as Rogers 4000 series and 3000 series & FR-4. This combination allows the ability to place digital control layers and r/f-microwave layers all on a single PCB saving space and cost. Common applications for these hybrid multi-layers include RF/ Microwave and broadband communication devices.
Cirexx International has worked with a number of prominent leaders in the RF / Microwave and broadband industry to develop unique processes that ensure tight control over complex areas such as "frequency filter zones" and specific dialectrics.
