Baseband Units (BBU)

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.
