Application Circuit

Note 1: Choose value of capacitor C1 for low frequency bypassing. A 0.01 μF ±10% capacitor is recommended.

Note 2: Pin 4 (Vctl) is the DC ground return for the circuit. The LNA is in the high gain mode when a short circuit is introduced to this

pin through an external switch. The LNA is in bypass mode when an open circuit is introduced. For the data presented, switching is

done through a two position DIP switch (J5) in series with a 2 Ohm resistor (to account for the Ron of an electrical switch).

Note 3: L1, L2 and C1 should be located as close to pins as possible.
