FUNCTION
Ground. Connect to ground plane with a low-inductance connection. Solder exposed paddle evenly
to the board ground plane.
RF Input Port to Amplifier. Requires a matching network and a DC-blocking capacitor that may be
part of this network. See Figure 1 for recommended component values.
Bias-Setting Resistor Connection. A resistor, R BIAS , placed from BIAS to ground sets the linearity
and supply current of the amplifier.
RF Open-Collector Output Port of Amplifier. Requires a matching network composed of an
inductance to V CC and a DC-blocking capacitor. See Figure 1 for recommended component
values.
Shutdown Control Logic-Level Input. A logic high enables the device for normal operation. A logic
low places the device in low-power shutdown mode.
Gain Control Logic-Level Input. A logic high places the device in high-gain mode. A logic low
places the device in low-gain mode, reducing the gain by 25dB.
Power Supply Input. Bypass directly to ground with a capacitor as close to the supply pin as
possible. See Figure 1 for recommended component values.
