SMW Ka LNB 25.50-27.00 GHz Earth Observation

Description

SMW Ka LNB 25.50-27.00 GHz Earth Observation PLL LNB The SMW Ka LNB 25.50-27.00 GHz Earth Observation model is a precision downconverter developed for satellite remote sensing and Earth-observation applications. It combines high dynamic range with auto-switching between internal and external 10 MHz references and includes Modbus RTU RS-485 monitoring & control. The design offers excellent linearity, low phase noise, and robust performance under extreme temperature conditions.
