RMS RF Power Detector is integrated with directional bridge-based coupler.

Press Release Summary:

Capable of simultaneously measuring forward and reverse RMS power levels with return loss in a single path down to 9 KHz, ADL5920 RMS RF Power Detector is operated in -40°C to +85°C temperature range with 5 V supply voltage and draws 150 mA current. Offering maximum +30 dBm input signal, unit comes in 32-lead, 5 mm x 5 mm LFCSP and supports small form factors. Unit combines sensing and detection function in space-critical applications for delivering an output to driving ADC directly.

Original Press Release:

Analog Devices’ Wideband RF Power and Return Loss Measurement System Offers Smaller Form Factor and Faster Time to Market

Analog Devices, Inc. today introduced a 9 KHz - 7 GHz directional bridge and dual RMS RF power detector that can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss. The new ADL5920 detector represents a change to conventional approaches by 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 drive a precision analog-to-digital converter (ADC) directly. 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 faster product time to market.
