Description
- CN-0399, Application circuit is an RF power measurement circuit that accurately measures the power from an RF signal source within a frequency range of 9 kHz to 6 GHz, and has a nominal input power range of 45 dBm (-30 dBm to +15 dBm). This circuit constitutes a complete rms RF power meter in a tiny form factor that can be powered entirely from a 5V USB power supply. The measurement signal chain consists of an rms responding RF power detector and a 12-bit, precision analog-to-digital converter (ADC). These devices are powered by a CMOS linear regulator which generates 3.3V from the 5V USB supply
