SMW X LNB 7.25-7.75 GHz 1 Band | Gen 2

Description

SMW X LNB 7.25-7.75 GHz 1-Band PLL LNB The SMW X LNB 7.25-7.75 GHz 1-Band is a precision low-noise downconverter designed for professional X-band satellite applications. It features an external 10 MHz or 100 MHz reference with automatic fallback to internal ±25 ppm reference, integrated RS-485 Modbus RTU monitoring, and sum alarm outputs. With ultra-low noise, excellent image rejection, and high linearity, it ensures stable performance in mission-critical SATCOM and Earth-observation systems.
