RF PCB – Radio Frequency Printed Circuit Boards

Image
  Radio frequency printed circuit boards ( RF PCBs ) are an exciting, fast growing sector of the PCB manufacturing industry. They are also incredibly complex with a dizzying range of options. The engineers at San Francisco Circuits can assist you with every step of the fabrication and assembly process, including material selection and key RF PCB manufacturing challenges to be aware of. What is an RF Circuit Board? In general terms, the PCB industry considers an RF circuit board to be any high frequency PCB that operates above 100MHz. Within the radio frequency class, anything above 2GHz is a Microwave PCB. What is a Microwave PCB? The main difference between RF circuit boards and Microwave PCBs is in the radio frequency in which they operate. Microwave PCBs are classified as any RF circuit board operating above 2GHz. RF circuit boards and Microwave PCBs are used for communication signals in any application that requires receiving and transmitting radio signals. For example, some co...
