The LNA_024_004 is an amplifier designed for low noise high frequency application. By using SiGe technology in combination with an optimized circuit design, a noise figure down to 3.2 dB can be achieved. Furthermore it features a high band width of nearly 13 GHz. This predestines it for applications of wide band radar applications as well as for signal amplification in wireless communication systems.
The Low Noise Amplifier chip comprises a gain control function to choose between low- and high-gain mode, both providing a linear amplification. A power enable pin allows for switching between operational and power-down mode to minimize the noise load in case no signals are applied. The possibility of fast switching between on and off status also allows for a pulsed operation mode, e.g. for energy saving by using low duty cycles.
