A block diagram shows how space-saving Littelfuse components fit into advanced antenna systems (AAS) on cellular towers that deliver mobile broadband and 5G service. Our solutions include SIDACtor thyristors to handle ac switching for ethernet, resettable PPTC devices for overcurrent protection of power amplifiers, lightning protection solutions, and ESD suppressors to keep signals noise-free.

Baseband units (BBUs) convert communication signals into formats usable by remote radio and active antennas. This block diagram highlights electronic components Littelfuse can supply to help BBUs perform their essential function. Available products include SIDACTOR thyristor ac switches, TVS diodes that suppress ESDs and limit noise in signals, and gas discharge tubes for lightning protection.

Equip cellular towers with active antennas with electronics that withstand extreme temperatures and humidity. This block diagram highlights Littelfuse products that meet those demands. We make surge protective devices that use metal oxide varistors, gas discharge tubes, and TVS diodes to provide overvoltage and lightning protection. We also supply high-voltage fuses to protect signal amplifiers.

Keep power supplies and battery backups for telecom, datacenter, and cellular tower equipment online. Consult this block diagram to identify solutions for doing that. You will find Littelfuse MOSFETs current converters and Schottky diode rectifiers, thermistor temperature sensors, and several types of overcurrent and overvoltage protection, including resettable PPTC devices and TVS diode arrays.

Space-saving electronics Littelfuse provides for 5G small cell antennas include SIDACtor thyristor current switches and Nano fuses. This block diagram highlights additional solutions, such as ESD suppressors to keep noise out of signals received by antennas, diode arrays for overvoltage protection, and gas discharge tubes for lightning protection.
