These pins and package ground paddle

must be connected to RF/DC ground.

3

RF 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.

This pin is AC coupled and matched to 50 Ohms.

15

Vdd

Power supply voltage. Choke inductor and bypass

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.
