The EVAL-CN0178-SDPZ is an is an circuits from the lab engineered tested. Ready to integrate software calibrated, 50MHz to 9GHz, RF power measurement system (CN0178). This circuit uses the ADL5902 TruPwr detector to measure the rms signal strength of RF signals with varying crest factors (peak-to-average ratio) over a dynamic range of approximately 65dB and operates at frequencies from 50MHz up to 9GHz. The measurement result is provided as serial data at the output of a 12bit ADC (AD7466). A simple 4-point system calibration at ambient temperature is performed in the digital domain. The interface between the RF detector and the ADC is straightforward, consisting of two signal scaling resistors and no active components. In addition, the ADL5902 internal 2.3V reference voltage provides the supply and reference voltage for the micropower ADC. The AD7466 has no pipeline delay and is operated as a read only SAR ADC.
