AD8317ACPZ-R7

AD8317 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in either measurement or controller modes. Typical application includes RF transmitter, PA set point control and level monitoring, power monitoring in radio link transmitters, RSSI measurement in base stations, WLANs, WIMAX, and radars.
