The Ka-band LNB 24.2–25.2 GHz is a high-performance low-noise block downconverter designed for demanding RF applications. It converts incoming Ka-band signals into the 1.0–2.0 GHz intermediate frequency (IF) range using a high-stability 23.2 GHz local oscillator (LO). Designed for telecom networks, satellite broadcasting, and RF testing environments, this LNB ensures precise, low-noise signal downconversion.
