Function Description

Interface Schematic

1

RF IN

RF input pin. This part is designed such that 50Ω is the optimal source

impedance for best noise figure. Best noise figure is achieved with only a

series capacitor on the input.

GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

3

VREF

For low noise amplifier applications, this pin is used to control the bias cur-

rent. An external resistor can be used to set the bias current for any VBIAS

voltage. This device will have good gain and noise figure with ICC as low as

3 mA.

4 GAIN SELECT This pin selects high gain and bypass modes.

Gain Select<0.8V, high gain.

Gain Select>1.6V, low gain.

GND

Amplifier output pin. This pin is an open-collector output. It must be biased

to VCC through a choke or matching inductor.

Not connected.

This pad should be connected to the ground plane by vias directly under

the device.
