SHDN (Pin 1): 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 150k pull down resistor to
ensure that the part is in shutdown when no input is
applied.
GND (Pin 2, 5): Ground.
V
OUT
(Pin 3): Detector Output.
V
CC
(Pin 4): Power Supply Voltage, 2.7V to 6V. V
CC
should
be bypassed appropriately with ceramic capacitors.
RF
IN
(Pin 6): RF Input Voltage. Referenced to V
CC
. A
coupling capacitor must be used to connect to the RF
signal source. The frequency range is 300MHz to 7GHz.
This pin has an internal 250Ω termination, an internal
Schottky diode detector and a peak detector capacitor.
