High Frequency Signal RF Prototype FR4 Circuit Board PCB 9Ghz For Millimeter Wave Radar

9Ghz High Frequency Signal PCB for Millimeter Wave Radar

♦ 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℃.

♦ High-frequency PCB Design Principles

• • Impedance control: strictly match the design value (within ±10%).

  •  

    Via design: use less through holes, give priority to blind and buried holes, and complete plating.

  •  

    Shielding protection: key signals are grounded, and metal shielding covers are added when necessary.

  •  

    Thermal management: thermal expansion coefficient matching, and heat dissipation layers are added to key areas.
