This Ka-band LNB 28.2–29.2 GHz WR-28 N/F/SMA is a high-performance block downconverter designed for precise signal reception in high-frequency systems. With a 27.2 GHz local oscillator, it provides a 1–2 GHz IF output and features low phase noise, high gain (≥50 dB), and excellent gain flatness (±2 dB across the band). The converter supports output through SMA, N-type, or F-type connectors, making it ideal for flexible system integration.
