ADL5513-ACPZ-R7

1 MHz至4 GHz的， 80分贝对数检测器/控制器 1 MHz to 4 GHz, 80 dB Logarithmic Detector/Controller

GENERAL DESCRIPTION

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.
