In order to achieve required linearity, the transmitter may operate significantly backed off from the saturated power capability, even under peak power operation. Since the cost of a transmitter rapidly increases with its power handling capability, and the linearity requirements are translated into additional power requirements, a great deal of the cost of a transmitter may actually be associated with linearity rather than transmit power level. If the added cost to achieve necessary linearity through additional power capability is significant, linearizing the transmitter can be cost effective.
An output coupler has been added to allow sampling of the output signal, and the bottom half of the diagram delineates the feedback method that generates the two quadrature pairs of error signals in the same way as used in the Cartesian loop or EER methods. This feedback corrects for channel differences in the basic LINC transmitter, substantially improving performance. Since most of the signal processing is performed at the modulation frequencies, the majority of the circuit is available for ASIC implementation.
The sample distorted signal is then demodulated by mixing it with the original unmodulated carrier, resulting in distorted modulation in quadrature or I-Q form. These distorted I and Q modulations are then subtracted from the original I and Q modulation to generate error I and Q modulation (hence the name Cartesian), which will continuously correct the nonlinearity of both the power amplifier and the I-Q modulator. Loop gain and phase relationships are critical to the design, and as with any feedback scheme, care must be taken to prevent loop oscillation.
