SMW Ka System 17.30-22.30 GHz Triple

SMW Ka System 17.70 – 21.30 GHz Triple PLL System

The SMW Ka System 17.70–21.30 GHz Triple is a high-performance Ka-band receiver system designed for multi-transponder satellite downlink applications. It integrates a wideband Ka LNA with isolator and three precision Ka-band block downconverters, offering full 17.7–21.3 GHz coverage with ultra-low phase noise meeting DVB-S2X profiles. The system includes matched HF and DC cables, auto 10 MHz external reference fallback, and optional RS-485 (Modbus RTU) monitoring for superior control and reliability.
