ADI Launches Wideband RF Power and Return Loss Measurement System

Analog Devices has launched 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 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, this 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

  • Allows for coupled power measurements down to 9 KHz
  • Maximum input signal: 30 dBm with handling capability for open and shorted loads
  • Requires a 5 V supply and draws 150 mA
  • Supplied in a 32-lead, 5 mm x 5 mm LFCSP, for the operating temperature range of -40°C to +85°C
