Directional bridge and dual RMS RF power detector raises integration level

Analog Devices’ wideband RF power and return loss measurement system integrates a directional bridge-based coupler, resulting in a smaller form factor and faster time to market, says the company.

The ADL5920 9kHz to 7GHz directional bridge and dual root mean square (RMS) RF power detector can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss. The detector represents a change to conventional approaches, says Analog Devices, 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 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.

The ADL5920 allows for coupled power measurements down to 9kHz with a maximum input signal of +30dBm with handling capability for open and shorted loads. It requires a 5.0V supply and draws 150mA.

The ADL5920 is supplied in a 32-lead, 5.0 x 5.0mm LFCSP and operates over a temperature range of -40 to +85 degree C.
