Claim Text:
1. A method of defining a quasi iso-gain supply voltage function for an envelope tracking system comprising: capturing into a memory array iso-gain supply voltage values versus output power values and input power values over a predetermined input power range for a device under test (DUT); locating a minimum iso-gain supply voltage value within the memory array; replacing the iso-gain supply voltage values within the memory array with the minimum iso-gain supply voltage value for corresponding output power values that are less than an output power value corresponding to the minimum iso-gain supply voltage value; generating a look-up table (LUT) of iso-gain supply voltage values as a function of input power values from the iso-gain supply voltage values and input power values captured in the memory array; and writing the LUT to a tangible computer-readable medium.
