These pins and package ground paddle

must be connected to RF/DC ground.

3RF IN

This pin is matched to 50 Ohms with a 51 nH

inductor to ground. See Application Circuit.

7ACG

AC Ground - An external capacitor of 0.01μF to

ground is required for low frequency bypassing.

See Application Circuit for further details.

capacitor are required. See application circuit.

Pin Descriptions

Application & Evaluation PCB Circuit

Note 1: Choose value of capacitor C1 for low frequency

bypassing. A 0.01 μF ±10% capacitor is recommended.

Note 2: L1, L2 and C1 should be located as close to pins as

possible.
