General Description

The Low-Noise-Amplifier (LNA) is designed for minimum

noise figure and can be used for low power 2.4 GHz

solutions. It requires an external matching network to match

to the antenna – typ. 50 ohm.

Applications

-

LNA for wireless 2.4GHz solutions such as Bluetooth,

WLAN, ISM

Functional Description

The LNA has a single-ended input and output and uses

a cascoded transistor configuration (Figure1).

An integrated inductor represents the load of the LNA.

A separate bias pin is available to set the gain.

An external matching network is requited to match to the

antenna – typ. 50 ohm.

Figure 2 shows the layout of the LNA.
