Features: Can also be used as automatic gain control and automatic level control part. Can be widely used in RF signal detection, signal power measurement, environmental field strength detection. RF power meter has very good sensitivity. The greater the amplitude or power of the RF signal, the higher the output voltage, the output voltage is proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, the range of 70dB. brand new and high quality The product is used for RF signal power detection, detection frequency range 0.1 - 2.4GHZ, can detect power in -72dBm to -2dBm of a radio frequency signal, the RF signal into a for DC voltage output. Specifications: Working frequency: 0.1--2.5 (GHz) Measurement power: -72- (- 2dBm) Output voltage: 0.5--1.65V Detection slope: 18mV/dBm (typical value) Input impedance: 50 Power supply voltage: 7-15V Size: approx. 32x25mm/1.26x0.98in Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item. We are sure that the style is the same as the pictures show. Please allow slight dimension difference due to different manual measurements. Package includes: 1PC x RF Power Meter
