Description

The ADL5910 is a radio frequency (RF) detector that operatesfrom dc to 6 GHz. It provides a programmable envelope threshold detection function.The envelope threshold detection function compares the voltagefrom an internal envelope detector with a user defined inputvoltage. When the voltage from the envelope detector exceedsthe user defined threshold voltage, an internal comparator captures and latches the event to a set or 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 latchedevent is held on the flip flop until a reset pulse is applied.The RF input of the ADL5910 is dc-coupled, allowing operation down to arbitrarily low ac frequencies. It operates on a 3.3 Vsupply and consumes 3.5 mA. Power-down mode reduces thiscurrent to 100 ?A when a logic low is applied to the ENBL pin.The ADL5910 is supplied in a 3 mm ? 3 mm, 16-lead LFCSP for operation over the wide temperature range of ?40?C to +105?C.Applications Wireless power amplifier input and output protection Wireless receiver input protection RF pulse detection and triggering
