Hi all,
I have been looking for the answer to my question but no success so far. Hopefully you can help me out.
Let's assume we have 3 mobile operators each having GSM900, GSM1800, UMTS2100 and LTE2600, 35dBm on each of these output. These signals go to the input of 15.1/0.1 coupler (let's assume there's no combiner between the basestations and coupler). If we now want to use attenuator on 15.1 output, how many watts minimum does this attenuator have to be?
35dBm - 15.1dBm = 19.1dBm = 0.098W. We have 12 signals (GSM900, GSM1800, UMTS2100 and LTE2600, 3 operators) coming from basestations, so we have 12*0.098W = 1.18W on coupler output, so it means the attenuator has to be >=1.18W. Is this correct?
Phil
