The Introduction of Rogers RO4000 Series Material


Rogers' RO4000 series of hydrocarbon and ceramic packed laminates and semi-cured sheets offer industry-leading high frequency performance and low circuit processing costs, a material that is compatible with FR-4 processing processes, including PCB multilayer structures, without the need for special hole pretreatments similar to sodium etching. The RO4000 material has the characteristics required for microwave RF circuits, matching networks, and specific impedance transmission line design. RO4000? Series products provide dielectric constant of 2.55~6.15 and low z-axis thermal expansion coefficient, with better heat treatment ability than traditional PTFE material, compatible with lead-free welding process, and in accordance with UL 94 V-0 fire rating version. RO4000 series products are ideal for P2P, RFID, LNB and other applications. The introduction of model selection of RO4000 series is as follows:




RO4000 LoPro laminate

=RO4000 LoPro laminate uses Rogers' patented technology so that the treated reversed copper foil can be compared to the standard RO4000? Together, the substrate has lower conductor losses while improving heat treatment capabilities, resulting in lower insertion losses and better signal consistency, while retaining other advantages of the RO4000 series materials. The low dielectric loss makes the RO4000 series suitable for many high frequency applications where traditional circuit boards cannot meet the requirements. The dielectric constant of the material is stable over a wide frequency range, so it is an ideal substrate for broadband applications.


Product features:

Lower insertion loss for higher operating frequency design (support frequency up to 40GHz)

Passive intermodulation (PIM) values are lower for base station antennas
