Image Number 2 for United States Patent #6242976.
A linearized channel amplifier comprising a linear channel amplifier circuit 20 and a nonlinear linearizer circuit located immediately before a high power amplifier. A common control circuit controls the linear channel amplifier circuit and the nonlinear linearizer circuit. The linearized channel amplifier functions as a driver amplifier and improves the linearity and efficiency performance of the high power amplifier across a desired frequency bandwidth. The 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. An external personality plug may be to set the performance of the channel amplifier and linearizer.
