Key Product Advantages
1. Robust, Hardware-Level 5G Interference Rejection
This LNB tackles the industry-wide challenge of 5G interference at its source, featuring dual-layer protection against 5G IMT @3.5GHz signals.
  • Matrix Waveguide Transmission: The integrated waveguide structure provides initial, physical suppression of out-of-band interference at the input stage.
  • Built-in High-Performance Rejection Filter: By incorporating a passive filter directly into the LNB, the need for external mechanical filters is eliminated.
Even under extreme test conditions—with a 5G signal at -30dBm and a 3.5GHz frequency injected directly into the waveguide—the LNB guarantees:
  • No In-Band Intermodulation: Gain stability is maintained within the operational frequency band.
  • No Output Saturation: The LNB resists saturation, preserving signal integrity.
Result: Delivers a pure, stable, and reliable output signal even in complex and congested electromagnetic environments.
2. Exceptional High-Gain & Low-Noise Performance
Engineered for applications demanding superior signal-to-noise ratios and weak signal capture:
  • High Gain: 63dB (Typ.) - Capable of amplifying extremely weak satellite signals, ensuring stable reception by the subsequent modem or receiver.
  • Ultra-Low Noise Figure: 0.8dB (Max.) - Minimizes the noise added by the LNB itself, guaranteeing an optimal Carrier-to-Noise ratio (C/N). This directly translates to higher data reliability and clearer signal quality.
3. Highly Flexible Customization
Designed to meet diverse regional and application-specific requirements:
  • Broad Input Frequency Coverage: Standard support for 9.84~15GHz, with the ability to tailor the range for specific projects.
  • Extensive LO Selection: A wide array of standard Local Oscillator frequencies are available, and we also accept requests for custom LO frequencies.

Target Applications
  • Professional Satellite Earth Stations
  • Broadcast & TV Content Distribution
  • Scientific Research & Weak Signal Observation
  • Dense Urban Areas with High 5G Interference
  • Bi-directional VSAT Communication Systems
The WR75 Series is more than just an LNB; it is a comprehensive solution for modern satellite reception challenges. It uniquely combines hardware-based 5G interference rejection with the high gain needed for weak signal capture and the low noise required for superior signal quality. Backed by powerful customization capabilities, the WR75 Series is designed to perform flawlessly in the most demanding environments.
