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.
The MAX2016 uses a pair of logarithmic amplifiers to detect and compare the power levels of two RF input signals. The device internally subtracts one power level from the other to provide a DC output voltage that is proportional to the power difference (gain). The MAX2016 can also measure the return loss/VSWR of an RF signal by monitoring the incident and reflected power levels associated with any given load. A window detector is easily implemented by using the on-chip comparators, OR gate, and 2V reference. This combination of circuitry provides an automatic indication of when the measured gain is outside a programmable range. Alarm monitoring can thus be implemented for detecting high-VSWR states (such as open or shorted loads).
The MAX2016 operates from a single +2.7V to +5.25V* power supply and is specified over the extended -40°C to +85°C temperature range. The MAX2016 is available in a space-saving, 5mm x 5mm, 28-pin thin QFN.
