An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB. Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?
The 1 dB compression point of an amplifier indicates the output power level at which the amplifier's gain drops by 1 dB from its linear gain, signaling the onset of non-linear behavior and potential distortion.
Given a 1 dB compression point of 32 dBm and a gain of 20 dB, the maximum linear input power can be calculated as:
To ensure operation within the linear region and avoid spectral regrowth, it's advisable to operate the amplifier below this threshold.An input power of 0 dBm provides a safe margin, ensuring signal integrity for a 24 Mbps 802.11g transmission.
