SMW Q LNB 37.50-42.50 GHz 2-5 Band

SMW Q LNB 37.50 – 42.50 GHz 2-5 Band PLL LNB

The SMW Q LNB 37.50 – 42.50 GHz 2-5 Band is a multi-band, high-performance Q-band LNB covering up to five sub-bands across 37.5 – 42.5 GHz. It features ultra-low phase noise, external 10 MHz reference with internal fallback, and RS-485 (Modbus RTU) monitoring & control. The switchable LO frequencies and automatic temperature-compensated gain make it ideal for flexible gateway, 5G-backhaul, and high-throughput SATCOM networks.
