Product Overview
The high-stability low‑noise block downconverter (LNB) processes weak incoming satellite signals from the primary feed source through dense multi-stage low‑noise amplification and high-precision down‑conversion down to the intermediate frequency band. These specialized original equipment manufacturer receiver components are widely deployed across satellite ground tracking stations, mobile satellite communication systems, and professional maritime communication arrays to optimize overall link margin profiles.
Key Features
Featuring wide operational bandwidth, low noise figure parameters, suppressed phase noise profiles, and a compact mechanical size, our modules deploy state-of-the-art microassembly technology for ultimate hardware reliability under extended outdoor use. Fully customizable frequency bands (C-band, X-band, Ku-band, etc.) and factory-preset gain options can be configured upon project engineering evaluation.
Typical Specifications
Typical Standard Indicators: Noise Figure ≤0.8 dB, Gain ≥55 dB, Output P1dB ≥+10 dBm, and LO phase noise ≤ -85 dBc/Hz @1kHz. We fully support custom configuration adaptations built to match your existing tracking infrastructure. Please contact our support desk for official technical data sheets or comprehensive factory price requests.
All OTA models share the functional requirements listed above. Customization (frequency band, gain, connectors) available upon request.
