ADL5904 RMS Responding Detector with Threshold Detection

Analog Devices offers their dual-function, radio frequency (RF), DC to 6 GHz TruPwr™ detector for RF and microwave applications

Image of Analog Devices' ADL5904 RMS Responding DetectorADI’s ADL5904 is a dual-function, radio frequency (RF), TruPwr™ detector that operates from DC to 6 GHz. It provides RMS power measurement along with a programmable envelope threshold detection function. The RMS power measurement function has a 45 dB detection range, nominally from -30 dBm to 15 dBm. The RMS power measurement function features low power consumption and an intrinsically, ripple-free error transfer function.

The envelope threshold detection function compares the voltage from an internal envelope detector with a user-defined input voltage. When the voltage from the envelope detector exceeds the user-defined threshold voltage, an internal comparator captures and latches the event to a set / reset (SR) flip-flop. The response time from the RF input signal exceeding the user-programmed threshold to the output latching is 12 ns. The latched event is held on the flip-flop until a reset pulse is applied.
