Product Details

The ADL5920 is an ultra-wide band bi-directional bridge detector that can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss.

The forward and reverse power in the bridge is measured using two high range RMS detectors. The ratio of the forward and reverse power levels is also measured and provided as a differential output voltage with an adjustable common mode level.

The bridge and detector circuitry is internally DC coupled to allow for frequency measurements down to 9 KHz. By applying an optional -2.5V negative supply, ground referenced dc-coupled signals can be applied.

The miximum input signal on each of the RF ports (RFIP and RFOP) is +30 dBm with handling capability for open and shorted loads.

The ADL5920 requires a 5V supply and draws 150 mA. It can be powered down via a PWDN pin.

The ADL5920 is supplied in a 32-lead, 5 mm x 5 mm LFCSP, for the operating temperature range of –40°C to +85°C.

Applications

  • Broadband In-Line Power and Return Loss Measurement in Wireless Transmitters
