DESCRIPTION
Resistor Bias Control. Connect a resistor, R BIAS , from BIAS to ground. R BIAS sets IP3 and supply
current. The current through this pin is approximately 60mV divided by R BIAS (see Applications
Information ).
Ground. For optimum performance, provide a low-inductance connection to the ground plane.
Amplifier Input. AC-couple to this pin with a DC blocking capacitor. External matching network is
required for optimum performance.
Supply Voltage. Bypass with a capacitor directly to ground at the supply pin. Refer to V CC Line
Bypassing section for more information.
Amplifier Output. AC-coupled internally.
