Applications
The ADL5910 is an envelope threshold detector that operates from DC to 6 GHz. The RF input signal drives an internal envelope detector. The output voltage from this envelope detector drives a comparator which is also driven by a user-defined input voltage. When the voltage from the envelope detector exceeds the user-defined threshold voltage, the event is latched to an S-R flip flop. The response time from the RF input signal exceeding the user-programmed threshold voltage to the output latching is 20 ns. The latched event is held on the flip-flop until a reset pulse is applied.
The RF Input of ADL5910 is dc-coupled, allowing for operation down to arbitrarily low input frequencies. It operates on either a 3V or 5V supply and consumes 2.5 mA. A disable 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 −55°C to +125°C.
