ANALOG DEVICES ADL5920ACPZ

ADL5920 is an ultrawideband, bidirectional detector that simultaneously measures forward and reverse rms power levels in a signal path, along with the return loss. The forward and reverse power traveling through the integrated bidirectional bridge is measured using two 50dB linear in dB rms detectors. The detector output voltages, available at the VRMSF and VRMSR pins, are proportional to the forward and reflected power in dBm. A third, differential, output produces a voltage proportional to the return loss (reflection coefficient) in dB, closely related to the voltage standing wave ratio (VSWR). It is used in application such as industrial metering, broadband inline power and return loss measurement, transmit power control and automatic level control in wireless transmitters, signal generators, network analysers, and wireless communications testers, condition based monitoring of system modules, cables, and connectors etc.
