It depends on the exact parameters of the signal you're transmitting,
especially PAPR (Peak to Average Power Ratio). Here are some spectrum
analyzer plots for a wideband digital signal. The B210 gains are set to
78, 83 and 85. Note that a 2 dB increase from 83 to 85 causes a 10 dB
increase in I
Hi fan,
In 2020, Alekh Gupta wrote a predistortion module for exactly that purpose.

Your questions regarding gain make no sense, because the whole point of
nonlinearity is
that you can't represent it as a single gain number, so you might need to read
up on th
Hi,everyone.I am trying to study how to pre distort the signal on b210 to
eliminate the error of nonlinear PA. Before that, I need to determine: does the
TX PA of b210 have nonlinear characteristics (when TX gain is too high, the
signal amplitude will be limited below 1. Is this becausof its non
