RF
coupling capacitor must be used to connect to the RF
signal source. The frequency range is 300MHz to 7GHz.
This pin has an internal 500
Schottky diode detector and a peak detector capacitor.
GND (Pin 2): Ground.
SHDN (Pin 3): Shutdown Input. A logic low on the SHDN
pin places the part in shutdown mode. A logic high enables
the part. SHDN has an internal 160k pulldown resistor to
ensure that the part is in shutdown when no input is
