Power Supply Voltage, 2.7V to 6V. has an internal 160k pulldown resistor to ensure that the VCC should be bypassed appropriately with ceramic detector is shutdown when no SHDN input is applied. In capacitors. shutdown VOUT is connected to ground via a 280Ω resis- tor. Channels can be shut down independently.

VOUT Offset Voltage Adjustments. These pins adjust the starting VOUT voltage when no RF
RFIN1, RFIN2 (Pins 12, 9):
RF Input Voltage. Referenced signal is present. For VOS from 0V to 130mV, VOUT is to VCC. A coupling capacitor must be used to connect to unaffected by VOS. For VOS > 130mV, VOUT is the sum of the RF signal source. These pins have internal 500Ω VOS plus the detected RF signal. terminations, Schottky diode detectors and peak detector capacitors.
