Functional Blocks:

The OneBase™ Cell Extender subrack is comprised of the following functional blocks:

− RFIM (Radio Frequency Interface Module):

− MCPAs (Multi-carrier Power Amplifiers—850 MHz or 1900 MHz)

− SCM (Switch Combiner Module)

− Filter Module (850 MHz or 1900 MHz)

− PDP (Power Distribution Panel)

− Inputs and Outputs

Inputs and Outputs:

The amplifier is powered from a DC supply voltage which can range from 20VDC-to-

30VDC (with a nominal voltage of 27 VDC). The DC power is brought into the subrack

at a terminal that is in the back of the subrack.

The RF signal is brought into the RFIM, passes into the amplifers, then through the SCM

which is blind-mate connected to the amplifiers, and finally into the Filter Modules and

subsequent antenna ports.
