GENERAL DESCRIPTION
The 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.
The RF input of the ADL5904 is dc-coupled, allowing operation
down to arbitrarily low ac frequencies. It operates on a 3.3 V
supply and consumes 3.5 mA. A disable mode reduces this
current to 100 µA when a logic low is applied to the ENBL pin.
The ADL5904 is supplied in a 3 mm × 3 mm, 16-lead LFCSP for
operation over the wide temperature range of −40°C to +105°C.
