This Ka-band LNB is purpose-built for advanced satellite communication, remote sensing, radar, and telemetry systems. It ensures high signal integrity through its low noise figure (≤3.0 dB) and stable LO frequency (±1 ppm). Its 50 dB gain and extended operating range from –30 °C to +60 °C make it ideal for professional, field, or lab-based deployments. The WR-28 waveguide input ensures optimal Ka-band reception, while multiple connector options enable flexible integration.
