Description
Positive Supply Voltage.
Power Ground.
Power Ground. May be left floating in case grounding is not feasible.
The device is enabled for EN = High, and in shutdown mode for EN = Low. EN
should be <2.5V for having low I_EN. For EN >2.5V, I_EN increases slightly, while
device is still functional. Absolute maximum rating for EN = 3.6V.
RF input signal to the detector, internally terminated with 50Ω.
Ground referenced detector output voltage.
