Wideband RF power measurement system offers smaller form factor


Analog Devices has introduced a 9KHz-7GHz 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 analogue-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:

  • Allows for coupled power measurements down to 9KHz
  • Maximum input signal: +30dBm with handling capability for open and shorted loads
  • Requires a 5V supply and draws 150mA
  • Supplied in a 32-lead, 5x5mm LFCSP, for the operating temperature range of -40 to 85°C.
