RF AUTOMATIC GAIN CONTROLLER

(RF-AGC), 700 - 3000 MHz

Pin Number

Function

Description

Interface Schematic

1, 3, 5, 8, 15, 17,

24, 26, 28, 30

GND

These pins and package bottom must be connected to RF

ground.

2, 29

ATTN2OUT,

ATTN1OUT

These ports are matched to 50 Ohms.

Blocking capacitor is required.

4, 9, 31

VDD

Power supply for the attenuator. External bypass

capacitors are required. See application circuits.

6, 32

ATTN2IN,

ATTN1IN

These ports are matched to 50 Ohms.

Blocking capacitor is required.

7

VCTRL

Attenuation control voltage for the attenuator.

0V for minimum attenuation, 5V for maximum attenuation.

10, 11, 12, 22

N/C

No connection required. These pins may be connected to

RF ground without affecting performance.

13

DETOUT

Logarithmic output that converts the input power to a DC

level in detector mode. Output voltage increases with

increasing amplitude.

14

DETVDD

Power supply for the logarithmic detector. External by pass

capacitors are required. See application circuit.

16

DETIN

Detector RF input pin.
