No matter you are designing a aerspace related product, or millimeter wave communication device, the performance of High Frequency PCB is a important factor which effect the stability of your system. There’s many material for High Frequency PCB, but we recommend RO4350B and RT/duroid 5880.
--------------------------------------------------------------------------------------
RO4350B, Widely used for mixed PCB(RO4350B + FR4)
RO4350B is a composite material which include proprietary glass fiber reinforced, ceramic/hydrocarbon, it’s OK to mix with FR4 material.
Features and Benefits
✔ Electrical Performance
Dk 3.48 ± 0.05, Df 0.0037 @ 10GHz
✔ Convenient Processing
Similar with FR4 PCB processing, it’s cheaper than traditional high Frequency PCB
✔ Stable
32 ppm/°C, suitable for applications which request high precision
✔ Safety
UL 94 V-0, suitable for active devices and high power RF designs
RO4350B PCBs are widely used in wireless communication equipment, radar systems, high-speed data transmission equipment, test and measurement equipment, microwave circuits, aerospace, and automotive electronics. In these fields, RO4350B is used to fabricate critical circuit boards for microwave point-to-point connections (P2P), automotive radars and sensors, radio frequency identification (RFID) tags, cellular base station antennas, and power amplifiers, demonstrating its excellent performance and wide application potential.

RT/duroid 5880, for higher level market
RT/duroid 5880 is a PTFE composite material.
Features and Benefits
✔ Electrical Performance
Dk 2.20 ± 0.02, Df 0.0009 @ 10GHz
✔ Convenient Processing
Easy to cut, showing good resistance to solutions and reagents used in etching, plating edge treatments and over-hole processes.
✔ Environmental Adaptation
Low moisture absorption rate, suitable for use in high humidity environments, maintaining the stability of electrical performance.
✔ Mechanical Performance
High strength, high stiffness, good heat resistance and chemical resistance ensure the durability and reliability of the material in complex working environments.
RT/duroid 5880 PCBs are widely used in wireless communications, satellite communications, radar, microwave communications, and medical electronics due to their excellent performance. Specific application scenarios include commercial aviation telephone circuits, microstrip and stripline circuits, millimeter-wave applications, military radar systems, etc., which meet the stringent requirements for high-frequency, high-speed, and high-precision signal transmission in these fields.
