NOTES
1
This note pertains to Step/Formula 1: For PA_Output_Power, if in the U.S. use Column A. If outside the U.S., as a
precaution contact Navini Technical Support (Engineering) for sign-off. The value input cannot be more than the
value shown in Column B.
2
This note pertains to Step/Formula 1: BTS_Loss is either (a) loss with a filter - i.e., if operating in the U.S. or other
market that requires a filter, or (b) loss with a bypass cable. The first number (+1) is the correct value if a standard
filter is used. The second number (0.4) is the correct value if a bypass cable is used. In Column D, for a 2.3 GHz
system the values are the same for both the 8-carrier and the 10-carrier systems.
3
Min loss in Cal Board is 27 dB. Max loss in Cal Board is 31 dB.
4
In the EMS the backplane loss will show 5.0 as default. Actual measured loss will be indicated on the back of the
chassis.

* The lowest value at which 2.3, 2.5, and 2.6 EFGH PA’s will shut down automatically. There is no auto shutdown for 2.4 and 2.6 EF combo systems.
** The value at which the bypass does not meet FCC limits.
***Passive configurations of BTS affect system Noise figure. For passive systems other than 2.4, consult SYSTEMS ENGINEERING.
