Maximum Output Power per Carrier at RAU
7.1 Maximum Output Power per Carrier at RAU
The following tables show the recommended maximum power per carrier out of the
RAU SMA connector for different frequencies, formats, and numbers of carriers.
These limits are dictated by RF signal quality and regulatory emissions issues. The
maximum input power to the Main Hub is determined by subtracting the system gain
from the maximum output power of the RAU. For most systems the gain is 0 dB.
Exceptions are the duplex port for the Cellular LGCell (30 dB gain) and the duplex
port of the PCS LGCell (40 dB gain).
Therefore, when you connect a Main Hub to a base station or repeater, the RF power
per carrier usually needs to be attenuated in order to avoid exceeding the LGCell’s
maximum composite output power.
Refer to Section 7.6, “Designing for a Neutral Host System,” on page 7-48 when
combining frequencies or protocols on a single Main Hub.
WARNING: Exceeding the maximum input power could cause perma-
nent damage to the Main Hub.
