RO4350B High Frequency PCB For Communication Equipment

♦ What's High-Frequency PCB?

High-frequency PCB is a special circuit board designed for high-frequency electromagnetic scenes, suitable for high-frequency (frequency>300MHz, corresponding to wavelength <1 meter) and microwave (frequency>3GHz, corresponding to wavelength <0.1 meter) fields. It is based on microwave substrate copper clad laminate, combined with some processes of ordinary rigid circuit board manufacturing, or made through special processing.

♦ Features of High-Frequency PCB

• • Special materials: use low Dk/Df substrates such as PTFE, ceramic filling materials, LCP, etc. to reduce signal attenuation (PTFE is the first choice for 5G).

  • Precise transmission: impedance control of ±5%, micron-level line accuracy, 30%+ loss reduction in millimeter wave band, and excellent phase stability.

  • Complex process: laser drilling accuracy of ±3μm, plasma etching instead of pickling, multi-layer board integrated passive devices, and high-yield production in dust-free workshops.

  • Strong heat dissipation: metal substrate + thermal simulation + phase change material, adapting to extreme environments from -55℃ to 125℃.

♦ Applications of High-Frequency PCB

• • ​Wireless communication: such as base stations, satellite communications, cellular networks, mobile phones, etc., used to transmit and process high-frequency radio waves, such as RF modules and antenna feeder networks of 5G base stations.
  • ​​Radar systems: including radars in the military and aerospace fields, as well as automotive collision avoidance systems, which can ensure the accuracy and reliability of radar signals.
  • ​​Medical equipment: Processing high-speed data in high-end medical equipment such as MRI and CT
