Cellular Towers with Active Antennas

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.
