The RevGo Ku- and Ka-Band Low Noise Blocks (LNBs) are high-performance, rugged receivers designed for VSAT, maritime, SNG, and teleport applications.
Advantages :
- Low noise figure: typically 0.8 dB for Ku-Band, ≤1.5 dB for Ka-Band.
- High LO stability: PLL design, ±1 to ±3 ppm.
- Compact and lightweight designs, IP65 sealed housings.
- Flexible options: single-band, dual-band, tri-band, or quad-band models.
- Reliable performance: <0.25% field failure rate thanks to strict quality processes.
Main Features :
- Input frequency ranges: - Ku-Band: 10.7–12.75 GHz - Ka-Band: 17.7–21.2 GHz (depending on version)
- Output IF: 950–2150 MHz.
- Gain: 55–65 dB (depending on model).
- Phase noise: better than IESS-308/309 standards.
- Power supply: 12–24 VDC via IF.
- Connectors: WR75 or WR42 waveguide input; F-type or N-type IF output.
- Operating temperature: -40 to +60 °C.
Typical Applications :
- VSAT terminals (fixed, portable, transportable).
- Maritime satellite communications.
- SNG and broadcast contribution.
- Teleport and gateway stations.
