High frequency PCBs are specialized circuit boards designed to transmit signals over a gigahertz (GHz) frequency range, ensuring quick and reliable communication in devices ranging from military radar systems to smartphones.
Radio frequency (RF) and microwave (MW) circuits can be found in countless wireless products, from handheld devices used in medical and industrial applications to advanced communications systems used in base stations, radar and global positioning. The success of these high-speed products begins during the product design phase when selecting PCB laminate materials
Frequency range: Generally speaking, high-frequency boards can be defined as PCBs with a frequency above 1GHz. They are mainly used in PCBs in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHz or wavelength less than 0.1 mete
RO4000 series laminates can be processed using standard FR-4 techniques without specialized via preparation. They are rigid, thermoset laminates, compatible with automated systems and scrubbing equipment for copper surface preparation. RO4835 laminates are RoHS compliant and suitable for UL 94V-0 certified applications.
RO4000 hydrocarbon ceramic laminates are designed to offer superior high frequency PCB performance and low cost circuit fabrication. The result is a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes offered at competitive prices.
Automotive radar technology is on the rise. Whether it is for current blind spot detection systems or for developing autonomous driving control, high performance, high reliability, compact size, and low cost are indispensable factors and motivations for the continuous development and improvement of core automotive radar technologies.
