Preliminary

Pin Function Description

Interface Schematic

1

VREF/PD For low noise amplifier applications, this pin is used to control the bias

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

VPD voltage.

VREF/PD

2

GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

3

RF IN

RF input pin.

4

To Bias

Circuit

RF IN

RF OUT

4

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

biased to VCC through a choke or matching inductor. This pin is typi-

cally matched to 50Ω with a shunt bias/matching inductor and series

blocking/matching capacitor. Refer to application schematics.

5

GND2

LNA emittance inductance. Total inductance is comprised of

package+bondwire+stripline (L1) on PCB.

6

SELECT This pin selects high gain and bypass.

Select < 0.8V, high gain.

Select > 1.8V, low gain.
