SMW Q LNB 37.50-42.50 GHz Wideband

SMW Q LNB 37.50 – 42.50 GHz Wideband PLL LNB

The SMW Q LNB 37.50 – 42.50 GHz Wideband PLL LNB is an advanced Q-band downconverter designed for high-throughput SATCOM gateways, 5G backhaul, and next-generation Ka/Q/V applications. It covers 37.5–42.5 GHz in two sub-bands (37.5–40.0 GHz / 40.0–42.5 GHz) with ultra-low phase noise, external 10 MHz reference with internal fallback, RS-485 (Modbus RTU) monitoring & control, and automatic temperature-compensated gain—offering unmatched stability and performance for demanding networks.
