Ku-Band Dual-LO LNB SatLNB-DKu Series

The SatHarbor SatLNB-DKu Series is a dual-local-oscillator Ku-Band Low Noise Block (LNB) designed for receiving satellite signals in two different Ku sub-bands: 10.70–11.70 GHz (Low) and 11.70–12.75 GHz (High). With a typical noise figure of 0.8 dB, gain ≥ 55 dB, and a 1 dB compression output power of at least 0 dBm, it delivers stable, high-quality signal downconversion. Featuring low power consumption (about 250 mA at 9–24 V DC), compact dimensions, optional 10 MHz external reference input, and compliance with RoHS standards, this LNB suits various fixed and mobile Ku-band satellite communication applications.
