Notes:
1. Nominal gain is the maximum gain at any frequency in the passband.
2. Nominal bandwidth is the difference between two frequencies that are adjacent to the passband where the amplification is 20 dB
lower than the passband amplification. One of the frequencies is lower than the passband and the other is higher.
3. The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier
signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can
cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.
4. The maximum power for 2 or more simultaneous signals will be reduced by 6 dB every time the number of signals is doubled.
