SMW Ka LNB 17.30–22.30 GHz 2 Band

Description

SMW Ka LNB 17.30 – 22.30 GHz 2-Band PLL LNB The SMW Ka LNB 17.30 – 22.30 GHz 2-Band PLL LNB provides precision dual-sub-band reception across the Ka-receive range. With auto-switching between internal and external 10 MHz references, excellent phase-noise performance meeting DVB-S2X profiles, and optional RS-485 M&C interface, it delivers high reliability for gateway and uplink monitoring applications.
