The ADL5910 is a radio frequency (RF) detector that operates from dc to 6 GHz. It provides a programmable envelope threshold detection 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 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 latched event 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 V supply and consumes 3.5 mA. Power-down mode reduces this current to 100 μA 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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The ADL5910-EVALZ is a fully populated, 4-layer, FR4 evaluation board that includes an SPST and an asymmetrical power coupling circuit. In its default configuration, the circuit operates as a complete input protection circuit that can connect to the input of a receiver or a power amplifier. A single 3.3 V power supply (VPOS) and GND test loops provide power for the complete board.
All documentation for the evaluation board is contained in the device datasheet.
