Maximum Output Power Per Carrier at RAU

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. System gain is software selectable
from 0 dB to 15 dB in 1 dB steps. Additionally, both the uplink and downlink of each
RAU gain can be reduced by 10 dB.
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 Unison’s maximum output
power recommendations.
Refer to Section 6.7, “Designing for a Neutral Host System,” on page 6-44 when
combining frequencies or protocols on a single Main Hub.
WARNING:
Exceeding the maximum input power could cause per-
manent damage to the Main Hub. Do not exceed the maximum com-
posite input power of 1W (+30 dBm) to the Main Hub at any time.
NOTE:
These specifications are for downlink power at the RAU output (excluding
antenna).
