when it says delivering 18dBm is that 18dB per microwatt?
why is power in positive dBm and whereas noise is generally in negative dB?
ACPR(adjacent channel power rejection) at 550kHZ offset is -21.4dBc
what's this ACPR? why at 550kHZ? what's dBc?
what's Frequency Offset/kHZ?
why generally, most power amplifier operate near 1dB compression point in order to achieve highest effiency?
And linearity is measured with third order harmonic intercept and 1dB compression point of fundamental frequency.
I can understand fundamental frequency but why pay attention to only third order instead of other orders?
