RFIN

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 Line

Bypassing section for more information.
