    Product Detail

    This Ku‑Band 10.95‑12.75 GHz Low‑Noise Block (LNB) supports single‑band and dual‑band operation. Single‑band provides three RF input bands: 10.95‑11.7 GHz, 11.7‑12.2 GHz and 12.25‑12.75 GHz. Dual‑band covers 10.7‑11.7 GHz and 11.7‑12.75 GHz with band switching controlled by +13/+18 VDC input voltage. Single‑band IF outputs are 950‑1700/950‑1450 MHz, while dual‑band delivers 950‑1950 MHz & 1100‑2150 MHz. Internal LO stability reaches ±0.5 ppm, with optional 10 MHz external reference. LO leakage is ≤‑30dBm at IF port and ≤‑60dBm at RF port. Conversion gain is selectable as 50‑60 dB or 55‑65 dB, output P1dB ≥10 dBm, featuring outstanding phase‑noise and spurious suppression performance.
    Power is fed over coaxial cable with 4 W power consumption. RF input adopts WR75‑G grooved waveguide. IF output is standard F‑type female, N‑type female is optional. Measuring 100×40×40 mm with IP65 waterproof rating, it operates reliably from ‑40℃ to +60℃ under condensing humidity conditions, widely used for Ku‑band satellite ground receiving terminals.
