Adjacent Channel Power Ratio (or ACPR)

A ratio in dBc between the measured power within a channel

relative to its adjacent channel.

Complex Modulation

The process of passing the real and imaginary components of a

signal through a complex modulator (transfer function = ejwt =

coswt + jsinwt) and realizing real and imaginary components

on the modulator output.

Complex Image Rejection

In a traditional two part upconversion, two images are created

around the second IF frequency. These images are redundant

and have the effect of wasting transmitter power and system

bandwidth. By placing the real part of a second complex

modulator in series with the first complex modulator, either the

upper or lower frequency image near the second IF can be

rejected.
