1、The product is designed by using AD8317 chip, and is used for RF signal power detection. 2、Can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output. 3、The greater the amplitude or power of the RF signal, the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, which ranges reac 4、It can be widely used in radio frequency signal detection, signal power measurement, environmental field strength detection. 5、It can also be used as part of automatic gain control and automatic level control. Features: The product is designed by using AD8317 chip, and is used for RF signal power detection. Can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output. The greater the amplitude or power of the RF signal, the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, which ranges reach 55dB. It can be widely used in radio frequency signal detection, signal power measurement, environmental field strength detection. It can also be used as part of automatic gain control and automatic level control. Application: RF transmitter PA set point control and level monitoring; Power monitoring in a radio line transmitter; RSSI measurements in base stations, WLAN, WiMAX, and radar Specification: Input impedance: 50 Ohms Output impedance: 50 Ohms (video impedance) Working frequency Freq: 1MHz ~ 10GHz Output voltage range: 1.6 ~ 0.4v (corresponding to -55 ~ 0 dBm) Input/output ratio: 22mv /dBm Input dynamic range: -60 ~ +5dBm (high linear dynamic range: -55 ~ 0 dBm) Power supply voltage: +3.3~5V.DC @20mA Size: 6.5*3.5cm/2.6*1.4in Weight: Approx.9g/0.3oz Package list: 1 x Logarithmic Power Meter
