HIGH FREQUENCY PRINTED CIRCUIT BOARDS
High Frequency PCBs are designed for high-speed, high-frequency signal transmission typically in the range
of 500MHz to 2GHz. These boards are essential for applications in RF (radio frequency), microwave, and
mobile communications, where signal integrity and transmission speed are critical. Unlike standard PCBs,
high-frequency boards require specialized materials like Rogers laminates to maintain stable electrical
performance and ensure minimal signal loss. Their design demands tight control over parameters such as
dielectric constant (Er), conductor width, and spacing, making precision fabrication crucial.
