Telecom Tower

 

Telecom Tower is designed to support antennas (also known as aerials) for telecommunications and broadcasting, including television. They are among the tallest man-made structures. Similar structures include electricity pylons and towers for wind turbines. Those towers are populated national wide for telecommunication system. In the structure of the telecommunication tower, power solutions are very critical ensuring the normal operation of the whole system. Fairchild is having the following solutions such as a complete power management ICs, Power MOSFETs and IGBTs plus analog and digital logic circuits available in the Telecom Tower applications.
