Brief Introduction of Communication PCB

Communication PCB (Printed Circuit Board) in the field of communication is the "highway subgrade" that supports the modern information society. They carry the core functions of all communication equipment, from smartphones and WiFi routers to 5G base stations, data center switches, and submarine fiber optic cable repeaters. Their core mission is to achieve lossless, high-speed, and stable signal transmission under high-frequency, high-speed, high-density, and highly reliable conditions.

The core challenge of communication PCB: the limits of speed and accuracy

Unlike consumer electronics or ordinary industrial PCB, communication PCB faces severe challenges brought by the continuous increase in signal speed (towards 100Gbps, 400Gbps or even higher) and frequency (millimeter wave frequency band):

The main application scenarios of Communication Station Signal

*Wireless communication:

*Base station: AAU (active antenna unit), BBU (baseband processing unit) core board, power amplifier board, filter board, antenna feeding network board.

Terminal devices: Smartphone motherboard, 5G CPE, cellular IoT module.

*Microwave/millimeter wave equipment: point-to-point feedback, satellite communication terminal.

*Wired communication/data communication:

Data switch/router: Core switch board, line card, management board, backplane (technology peak, multiple layers, high speed, high density, strict reliability requirements).

Optical Communication: Optical modules (SFP+, QSFP-DD, OSFP, etc.) internal PCB (high-speed SerDes channel), optical transceiver, OTN equipment.

Server/Storage: motherboard, acceleration card (GPU, FPGA), storage controller board, high-speed interconnect port board.

*Broadband access:

*Fiber to the Home: ONU/ONT (Optical Network Unit/Terminal), OLT (Optical Line Terminal) cards.

Cable modem/DSL modem: * * Internal motherboard.

Testing and measuring instruments:

*Internal high-frequency boards such as network analyzer, spectrum analyzer, high-speed oscilloscope, signal generator, etc.

*Satellite communication:

*High reliability and radiation resistant PCBs in satellite communication payloads and ground station equipment.
