AD8318 RF Logarithmic Detector 70dB, RSSI Measurement, Power Meter 1-8000MHz

The RF detector is based on the Analog Devices AD8318 chip. It is designed with a power supply voltage regulator that enhances detection accuracy against official specifications. The operating frequency range is 1-8000MHz. It can detect RF signals from -65 to +5dBm and converts them to DC voltage. The output represents the detected signal strength (in dBm, logarithmically detected), with the RF signal converted to a DC voltage output. The amplitude or power of the RF signal corresponds to the output voltage. Signal strength indication such as RSSI, spectrum analyzer, gain control, etc., is possible.

Specifications:

• Operating frequency: 1-8000MHz
• Dynamic range: -65dBm to +5dBm
• Detection slope: -25 mV/dB (typical)
• Output voltage range: 0.5-2.1V
• Power supply voltage: 7-15VDC (including power supply regulator circuit)
• Input impedance: 50 ohms
• RF interface: standard SMA female connector
