SMW Ka LNB 27.00-31.00 GHz 1 Band Uplink Monitoring

Description

SMW Ka LNB 27.00 – 31.00 GHz 1-Band Uplink Monitoring PLL LNB The SMW Ka LNB 27.00 – 31.00 GHz 1-Band Uplink Monitoring model is a professional low-noise downconverter for Ka-band uplink monitoring and gateway supervision. It features auto-switching between internal and external 10 MHz references, integrated Modbus RTU RS-485 M&C, and configurable alarms for LO lock, supply, or LNA status. The design offers high stability, low phase noise, and rugged construction for 24/7 monitoring environments.
