RO4350B LoPro Microwave PCB 30.7mil Rogers High Frequency PCB Reverse Treated Foil With ENIG for Digital Applications
(Printed Circuit Boards are custom-made products; the images and specifications shown are for reference only.)
Product Description
RO4350B LoPro laminates utilize proprietary technology from Rogers, allowing reverse treated foil to bond effectively with standard RO4350B dielectric. This results in a laminate that features low conductor loss, enhancing insertion loss and signal integrity while maintaining all the other desirable attributes of the standard RO4350B laminate system.
Features and Benefits
RO4350B materials are reinforced hydrocarbon/ceramic laminates with very low profile reverse treated foil, offering several key advantages:
Lower Insertion Loss:Improved signal transmission efficiency.
Low Passive Intermodulation (PIM):Enhances overall performance in RF applications.
Increased Signal Integrity:Ensures clearer signal transmission.
High Circuit Density:Supports complex circuit designs without compromising performance.
Thermal and Design Characteristics
Low Z-axis Coefficient of Thermal Expansion:Facilitates multi-layer board capability and design flexibility.
Lead-Free Process Compatible:Supports high-temperature processing and meets environmental regulations.
CAF Resistant:Increases reliability in harsh environments.
Typical Applications
1.Digital applications such as servers, routers, and high-speed backplanes
2.Cellular base station antennas and power amplifiers
3.LNBs for direct broadcast satellites
4.RF Identification Tags
