The ADL5513 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. The ADL5513 maintains accurate log conformance for signals greater than 4 GHz. The input dynamic range is typically 80 dB (re: 50 ) with error less than 3 dB. The ADL5513 has 10 ns response time which enables RF burst detection to a pulse rate of beyond 50 MHz. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions. A supply of 2.7 V to 5.5 V is required to power the device. Current consumption is less than 30 mA, and decreases to TBD A when the device is disabled.
