SMW Q LNB 37.50-42.50 GHz 1 Band

SMW Q LNB 37.50 – 42.50 GHz 1-Band PLL LNB

The SMW Q LNB 37.50 – 42.50 GHz 1-Band is a next-generation Q-band downconverter that covers the entire 37.5–42.5 GHz SATCOM receive range in a single unit. It offers external 10 MHz reference with internal fallback, RS-485 (Modbus RTU) monitoring & control, automatic temperature-compensated gain, and ultra-low phase noise performance—ideal for high-throughput, 5G-backhaul, and advanced gateway terminals.
