General Description

The MAX2016 dual logarithmic detector/controller is a fully integrated system designed for measuring and comparing power, gain/loss, and voltage standing-wave ratio (VSWR) of two incoming RF signals. An internal broadband impedance match on the two differential RF input ports allows for the simultaneous monitoring of signals ranging from low frequency to 2.5GHz.
