LTC5530
U U U PI FU CTIO S RFIN (Pin 1):
RF Input Voltage. Referenced to VCC. A ensure that the part is in shutdown when no input is coupling capacitor must be used to connect to the RF applied. In shutdown VOUT is connected to ground via a signal source. The frequency range is 300MHz to 7GHz. 280Ω resistor. This pin has an internal 500Ω termination, an internal
V
Schottky diode detector and a peak detector capacitor.
M (Pin 4):
Negative Input to Buffer Amplifier.
V GND (Pin 2):
Ground.
OUT (Pin 5):
Detector Output.
V SHDN (Pin 3):
Shutdown Input. A logic low on the SHDN
CC (Pin 6):
Power Supply Voltage, 2.7V to 6V. VCC should be bypassed appropriately with ceramic capacitors. pin places the part in shutdown mode. A logic high enables the part. SHDN has an internal 160k pulldown resistor to
