The NTUM30DA is a linear, multichannel power amplifier that operates with an instantaneous
bandwidth of 20 MHz (determined by the base station) in the 60 MHz frequency band from 1930
MHz to 1990 MHz. It provides either 30 watts (UMTS) or 45 watts of power, based on the select-
able operating mode. It provides for two RF inputs: a primary input and a redundant input.

Each amplifier module has a power, and data I/O connector that allows the host system to moni-
tor the amplifier module performance. Primary power for the amplifier is -48 Vdc.
