K-Band Low Noise Blocks (LNBs) are used in satellite communication systems that operate within the K-band frequency range. The K-band generally refers to frequencies between 18 GHz and 27 GHz. For satellite communication, the K-band is typically split into lower K-band (18-20 GHz) and upper K-band (20-27 GHz). K-band LNBs are used for high-capacity data transmission, broadband communication, and high-definition video services.

K-band is particularly suitable for applications requiring high data rates, such as broadband satellite internet, satellite TV, backhaul links, and military communication systems. LNBs designed for the K-band are essential for converting high-frequency signals received from satellites to lower intermediate frequencies that can be processed by ground equipment.
