2oz RO4003C Microwave High Frequency Printed Circuit Board For Radar System
2oz RO4003C Microvia Microwave High Frequency PCB Board For Radar System
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.

Product Description
Features of High-Frequency PCB
-
-
Special materials: Polytetrafluoroethylene (PTFE), PPO and other materials are often used, which have low dielectric constant, low loss factor, and thermal expansion coefficient similar to copper foil.
-
Strict impedance control: The impedance needs to be precisely controlled, usually within a tolerance of about 2% to ensure signal transmission stability.
-
Fine manufacturing process: High design and manufacturing precision, using micro-holes, blind holes and buried holes to increase line density and signal transmission efficiency.
-
Strong anti-interference: Improve anti-interference and electromagnetic compatibility through processes such as multi-layer printing
-
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 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
