Linearized channel amplifier
NettetDigital Predistortion (DPD) is used to linearize power amplifiers and enable a higher output power and efficiency while reducing the non-linearity to acceptable levels by the system integrators. The DPD applies a controlled distortion of the input signal to compensate for the non-linearity generated by the power amplifier at the output. NettetThe linearized channel amplifier employs low cost temperature compensation circuits in an interface circuit and a temperature compensation network circuit, and uses a novel methodology to provide for command and control functions that includes a measurement, analytical calculation and setting process.
