Analog Devices offers wideband RF power and return-loss measurement system

Norwood, MA (BUSINESS WIRE). Analog Devices Inc. has introduced a 9-kHz to 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 what the company calls 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.

ADL5920 product highlights include a maximum input signal of +30 dBm with handling capability for open and shorted loads. The device requires a 5-V supply and draws 150 mA. It is supplied in a 32-lead, 5-mm x 5-mm LFCSP; operating temperature range is -40°C to +85°C.
