Description
- CN-0150, Design Circuit measures RF power at any frequency from 1 MHz to 8 GHz over a range of approximately 60 dB. The measurement result is provided as a digital code at the output of a 12-bit ADC with serial interface and integrated reference. The output of the RF detector has a glue less interface to the ADC and uses most of the ADC input range without further adjustment. A simple two-point system calibration is performed in the digital domain
