Abstract:
A closed power control loop that produces a linear transfer function in response to an adjustable non-linear reference input, comprising:an adjustable power amplifier, wherein said adjustable power amplifier includes a power input, a control input and a power output; a power detector, wherein said power detector detects said power output of said adjustable power amplifier and produces a power detector output; an adjustable, non-linear reference signal; and a comparator wherein said comparator compares said power detector output with said reference signal and produces a comparator output representative of the difference between said power detector output and said reference signal, wherein said comparator output is provided to said power amplifier in the form of said control input and said power amplifier adjusts said power input with said control input to produce a non-linear power output variation, wherein said non-linear power output variation is substantially linear with respect to an adjustment in said non-linear reference signal said adjustable non-linear reference signal being provided by a programmable potentiometer (EEPOT).
