This professional-grade S-band Low‑Noise Block Downconverter (LNB) supports input from 2.0 GHz to 2.4 GHz and downconverts to 0.95 GHz – 1.35 GHz via a precise 3.35 GHz local oscillator. With ≥50 dB gain, excellent phase noise characteristics (–65 dBc/Hz @1 kHz, –80 dBc/Hz @10 kHz), and superior mirror channel suppression (≥40 dB), it’s built for high-performance applications in satellite communications, telemetry, and RF labs.
Key features:
– I/O: SMA, N‑type, F‑type
– LO frequency stability ≤1 ppm
– AGC range ≥25 dB
– Rugged enclosure for –30…+60 °C use, up to 95 % humidity
– Power: +12 V to +24 V, ≤350 mA
Our lab-developed LNBs include a 1.5‑year warranty and long-term 7‑year post-warranty service. Whether you’re a provider, integrator, or engineer — we’re here to support you.
