GENERAL DESCRIPTION  
The ADL59101 is a radio frequency (RF) detector that operates  
from dc to 6 GHz. It provides a programmable envelope  
threshold detection function.  
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 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  
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.
