1. A method of obtaining optimum RF performance for a slave base station when co-siting a master base station with said slave base station, said method comprising:

  • calculating the third order intercept (IP3) characteristics of the slave base station that is sharing an antenna assembly with said master base station;

    calculating the noise figure (NF) characteristics of the slave base station;

    plotting the IP3 and NF characteristics of the slave base station versus a range of upfront gain values;

    selecting a desired upfront gain value to achieve a particular IP3 and NF characteristic; and

    adjusting the upfront gain supplied to the slave base station to match the desired upfront gain.
