Function

Description

Interface Schematic

1VREF/PD

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 VPD

voltage.

2GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

3RF IN

RF input pin.

4RF 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 typically matched

to 50

Ω with a shunt bias/matching inductor and series blocking/matching

capacitor. Refer to application schematics.

5GND2

LNA emittance inductance. Total inductance is comprised of

package+bondwire+stripline (L1) on PCB.

SELECT

This pin selects high gain and bypass.

Select < 0.8V, high gain.

Select > 1.8V, low gain.
