LOW NOISE AMPLIFIER IN THE 24 GHz K-BAND – LNA_024_004

The RF Low Noise Amplifier LNA_024_004

The LNA_024_004 is an amplifier IC designed for low noise radio frequency applications in K-band. 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 RF wireless communication systems in the k-band.

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.
