LT5534
PIN FUNCTIONS EN (Pin 1):
Enable. When the input voltage is higher than
VCC (Pin 4):
Power Supply. This pin should be decoupled 0.9V, the circuit is completely turned on. When the input using 100pF and 0.1µF capacitors. voltage is less than 0.6V, the circuit is turned off.
RF (Pin 6):
RF Input. This pin is internally biased to
GND (Pins 2, 5):
Ground. VCC – 0.18V. A coupling capacitor must be used to connect
V
to the RF signal source.
OUT (Pin 3):
RF Detector Output.
