ADL5386
Component
P2
Description
Detector Controller Mode vs. Measurement Mode. When P2 is installed, the detector operates
in standalone measurement mode, measuring the signal strength on the DTIN SMA connector
and providing an output voltage on the VDET and VSET SMA connectors. To operate the
device in AGC mode, P2 should be removed, a sample of the output of the VVA is connected
to DTIN (using a directional coupler or a power splitter), and a setpoint voltage should be
applied to the VSET SMA connector. To operate the VVA in open-loop mode, disable the
detector by connecting TADJ to VP. DTIN should be ac-coupled to ground, and P2 should be
removed. The VVA control voltage (0 V to 2 V) is applied to VDET, which becomes an input. The
VSS1 terminal must be connected to a fixed 2 V source.
