Abstract
A method of obtaining optimum RF performance for a slave base station when co-siting a master base station with said slave base station involves calculating operating characteristics of the slave base station that is sharing an antenna assembly with the master base station. The third order intercept (IP3) and the noise figure (NF) characteristics of the slave base station are calculated and plotted versus a range of upfront gain values. The plots are studied and compared against vendor specifications and standalone performance characteristics. A desired upfront gain value is then selected to achieve a particular IP3 and NF characteristic for the slave base station. Upon selection, the upfront gain supplied to the slave base station is adjusted via an attenuator placed in-line before the slave base station to match the desired upfront gain.
