SYSTEM AND METHOD FOR INCREASING ACCURACY OF TRANSMITTER POWER DETECTION OVER A LARGER RANGE OF OUTPUT POWER LEVELS

摘要

A system and method for increasing accuracy of transmitter power detection over a larger range of output power levels wherein a diode detector is followed by a series cascade of 2 op amps. The first op amp functions as a differential/buffer amplifier, which improves temperature performance. The second op amp has two selectable gain factors. The output of the second op amp is routed to the ADC. A single control line is connected to a controllable switching device that configures the second op amp for high gain or low gain.
