Linear Technology 

LTC5536

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.

VM (Pin 3): Comparator Negative Input. Apply reference

voltage to this pin.

LEN (Pin 4): Latch Enable Input. Output is latched when

LEN is high and transparent when LEN is low.

VOUT (Pin 5): Comparator Output.

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

VCC should be bypassed appropriately with ceramic

capacitors.
