5 ATTENUATION CONTROL OF THE AMPLIFIER
The MirrorCell Select CDMA repeater offers 30dB of user-settable attenuation to
customize the desired output of the repeater. The amplifier can be attenuated in 2dB
steps, from 0dB to 30dB. Ortel recommends that you start with 30dB of attenuation and
slowly decrease attenuation, thereby increasing output power, in order to ensure the
repeater transmits only the desired amount, and not more. This will help to reduce
interference caused by too much output power.
The following table is a guideline for setting the attenuation.
