1 Low Power is defined here as a Standard MRAU used with Standard SRAUs; see Table 3 on page 19.
2 Medium Power is defined here as a High Power MRAU used with Standard SRAUs; see Table 4 on page 20.
3 High Power is used to define a High Power MRAU used with High Power SRAUs; see Table 5 on page 21.
4 See “System Gain Examples” on page 18.

System Gain Examples
System Gain is the addition of the RF DART gain + the RAU gain. This section provides examples of system gain,
based on the following specifications:
1 All Standard and High Power (HP) MRAUs and SRAUs have 0 db of RX gain
2 Standard MRAU and SRAUs have 0 dB of TX gain
3 The HP MRAU adds 3 dB of TX gain on its bands and all bands of Standard and HP SRAUs connected to it
4 HP MRAUs and HP SRAUs add an additional 5 dB of TX gain on the 1900, 2100, and 2600 RF bands
Example A: All RAUs RX Configuration
RX Gain 850 MHz band: -1 to 30 dB (RF DART gain) + 0 dB (Standard MRAU and SRAU gain) = -1 to 30 dB
Example B: Low Power Level Configuration: SPT-M1-8519-1 + SPT-S2-70AWS-1-SISO
TX Gain 850 MHz band: 9 to 40 dB (RF DART gain) + 0 dB (Standard MRAU gain) = 9 to 40 dB
TX Gain 1900 MHz band: 9 to 40 dB (RF DART gain) +0 dB (Standard MRAU gain) = 9 to 40 dB
TX Gain 700 MHz band: 9 to 40 dB (RF DART gain) + 0 dB (Standard
SRAU with Standard MRAU gain) = 9 to 40 dB
TX Gain 2100 MHz band: 9 to 40 dB (RF DART gain) + 0 dB (Standard
SRAU with Standard MRAU gain) = 9 to 40
