Description
Interface Schematic
1RF IN
RF input pin. This part is designed such that 50
Ω is the optimal source
impedance for best noise figure. Best noise figure is achieved with only a
series capacitor on the input.
2GND1
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
3VREF
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
3mA.
4GAIN SELECT This pin selects high gain and bypass modes.
Gain Select<0.8V, high gain.
Gain Select>1.8V, low gain.
5GND2
See GND1.
6RF OUT
Amplifier output pin. This pin is an open-collector output. It must be biased
to VCC through a choke or matching inductor.
7NC
Not connected.
8NC
Not connected.
Pkg
Gnd
GND
This pad should be connected to the ground plane by vias directly under
the device.
