• LNA fault alarm and power supply unitWith the rapid deployment of 5G networks in the C-band spectrum (3.4–4.2 GHz), satellite ground stations and sensitive RF receiving systems are increasingly vulnerable to strong out-of-band interference. The GARDINER 5G Interference Mitigation LNA​ integrates high-performance filtering technology to provide exceptional rejection of adjacent 5G signals while maintaining ultra-low noise figures, ensuring reliable signal reception and protecting backend equipment from saturation or damage.Key Features

  ■ Superior 5G Rejection: Deep attenuation of 5G cellular signals (e.g., >30 dB typical @ 3.4–3.8 GHz) to prevent LNA desensitization.

  ■ Ultra-Low Noise Temperature: Industry-leading noise performance (as low as 40 K typical) to maximize system G/T value.

  ■ High Gain Stability: Consistent gain performance (≥50 dB) across the full operating temperature range (-40°C to +70°C).

  ■ Robust Design: IP65-rated aluminum housing for harsh outdoor environments; compatible with standard waveguide (BJ40) and coaxial interfaces.

  ■ GARDINER Reliability: Engineered for mission-critical applications in satellite communications, broadcast, and telemetry.

  Typical Applications

  Satellite Earth Stations | VSAT Systems | Broadcast Uplinks/Downlinks | Telemetry & Command (TT&C) | Electromagnetic Compatibility (EMC) Testing

  Note: For optimal performance in dense urban or 5G-dense areas, selecting a GARDINER C-band LNA with integrated BPF (Band Pass Filter) is strongly recommended to mitigate interference risks.
