UltraFast™ 7ns Response Time 15GHz RF Power Detector with Comparator

Linear Technology 

LTC5564

PIN FUNCTIONS

RFIN (Pin 1): RF Input Voltage. A coupling capacitor must

be used to connect to the RF signal source. This pin has

an internal 250Ω termination, an internal Schottky diode

detector and an internal 8pF reservoir capacitor.

NC (Pins 2, 9, 16): No Connect. These pins should be left

unconnected by the user for best RF performance.

GND (Pins 3, 4, Exposed Pad Pin 17): These pins should

be tied to system ground. See Applications Information

for best practices.

LEN (Pin 5): Comparator Latch Enable Input. VCOMP will be

latched when LEN is high and transparent when LEN is low.

VOUTADJ (Pin 6): Amplifier Output Offset Adjust. When left

floating, the VOUT pin of the amplifier will be at its nominal

quiescent output offset value. See the Applications Infor-

mation section for adjustment range.

G0, G1 (Pins 7, 8): Amplifier Gain Selection. Logic low or

high levels on the G0 and G1 pins will change the internal

amplifier gain, bandwidth and slew rate characteristics. See

the Applications Information section for gain setting codes.

VOUT (Pin 10): Detector Amplifier Output.

VCCP (Pin 11): High Current Power Supply Pin.

VCCA (Pin 12): Analog Power Supply Pin.

VCOMP (Pin 13): Comparator Output.

VREF (Pin 14): Comparator Negative Input. Apply an ex-

ternal reference voltage to this pin.

VCCRF (Pin 15): RF Power Supply Pin.
