SMW X LNB 7.90-8.50 GHz 1 Band | Gen 2

SMW X LNB 7.90–8.50 GHz 1-Band PLL LNB

The SMW X LNB 7.90–8.50 GHz 1-Band PLL LNB is a precision low-noise downconverter engineered for X-band SATCOM and radar applications. It combines exceptional phase-noise performance with external 10 / 100 MHz reference (with automatic fallback to internal ±25 ppm), RS-485 Modbus RTU monitoring, and configurable alarms for LO lock, LNA, and voltage conditions.
