Base Band Unit

With the ever-increasing demand for the large and growing amount of voice and data traffic on the network, the nowadays telecommunication network must have powerful signal processing capabilities to handle this situation.

The telecom baseband unit (BBU) is the baseband processing unit of telecom systems. The BBU has many advantages such as modular design, small size, high integration and low power consumption. A typical wireless telecom station consists of the baseband processing unit (BBU) and the RF processing unit (remote radio unit - RRU).

Fairchild featured power management solutions provide optimized power to the Base Band Unit, which is listed as follows:
