Description
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.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
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 V
voltage. This device will have good gain and noise figure with I
3mA.
This pin selects high gain and bypass modes.
Gain Select<0.8V, high gain.
Gain Select>1.6V, low gain.
See GND1.
Amplifier output pin. This pin is an open-collector output. It must be biased
to V
Not connected.
Not connected.
This pad should be connected to the ground plane by vias directly under
the device.
