Analog Devices, Inc. (ADI) introduced a 9 kHz to 7 GHz directional bridge and dual RMS RF power detector that simultaneously measures forward and reverse RMS power levels in a signal path, along with return loss.
The ADL5920 detector is a change to conventional approaches, integrating a directional bridge-based coupler that results in an industry leading level of integration and bandwidth. For space-critical applications, the ADL5920 integrates the coupling or sensing function with the detection function and provides an output that can directly drive a precision analog-to-digital converter (ADC). For wideband operation or for frequency variants, the ADL5920 detector eliminates the need to choose a different directional coupler for each frequency. This integrated, wideband device supports smaller form factors and enables faster product time-to-market.
