PI FU CTIO S

RFIN (Pin 1): RF Input Voltage. Referenced to VCC. A

coupling capacitor must be used to connect to the RF

signal source. The frequency range is 600MHz to 7GHz.

This pin has an internal 500Ω termination, an internal

Schottky diode detector and a peak detector capacitor.

GND (Pin 2): Ground.

VOS (Pin 3): VOUT Offset Voltage Adjustment. From 0V to

200mV, VOUT does not change. Above 200mV, VOUT will

track VOS.

VM (Pin 4): Negative Input to Output Amplifier.

VOUT (Pin 5): Detector Output.

VCC (Pin 6): Power Supply Voltage, 2.7V to 5.5V. VCC should

be bypassed appropriately with ceramic capacitors.
