All three amplifiers are connected in series. I shall correct my statement: in the lab, we get 0dBm output on the last stage of amplifier. However, when we are at the site, it max at -24dBm (it is -ve, sorry). There is no difference in the configuration but number of channel.

Are you terminating the unused ports in the LAB? If the amplifier is 22dBm then 24dBm would be normal.

A question on the amplifer specifications. We are using a few amplifiers for our RX signal. The amplifier has 22dBm - 1dB compression point. We the have 5~6 channels input into the amplifers, we could obtain about 0dBm output power in the LAB. However, at the site, when we have total 16 channels input into the amplifiers, the output power per channel max. at 24dBm. Anybody could give some advices. Anybody could advise how could we get 0dBm output at the site? Best Regards, Chong Kwan Meng Real people. Real questions. Real answers.
