NOTE:
The LSB, USB, and in band intermodulation products are caused mainly by the
transmitter’s non-linear distortions due to poor power amplifier linearity and
phase distortion. They are mainly developed in the PA stage. If the amplifier is
substantially linear, the shoulders will be -36 dB or lower. As the non-linear dis-
tortions increase, the shoulder levels will rise above -36 dB. Unequal USB and
LSB shoulder levels indicate the presence of phase distortion.
