SMW X LNB 7.25-8.50 GHz 2 Band | Gen 2

SMW X LNB 7.25 – 8.50 GHz 2-Band PLL LNB

The SMW X LNB 7.25 – 8.50 GHz 2-Band PLL LNB is a dual-band X-band low-noise downconverter designed for professional SATCOM and Earth-observation systems. It covers two switchable input bands, 7.25–7.75 GHz and 7.75–8.50 GHz, providing outstanding stability, low phase noise, and remote monitoring via RS-485 (Modbus RTU). The unit includes external 10 / 100 MHz reference with internal fallback, and sum alarm functionality for LNA, LO lock, voltage, and signal monitoring.
