Power detection works across 9kHz to 7GHz in both directions

Analog Devices has introduced a 9KHz-7GHz directional bridge and dual RMS RF power detector that can simultaneously measure forward and reverse power levels in a signal path along with return loss. ADL5920 detector represents a change to conventional approaches by integrating a directional bridge-based coupler which integrates the coupling or sensing function with the detection function ...
