SMW C LNB 3.40–4.80 GHz 2 Band

The SMW C LNB 3.40–4.80 GHz 2 Band, manufactured by Swedish Microwave AB, is a professional C-band Low Noise Block (LNB) designed for satellite reception systems requiring flexible frequency coverage and reliable RF performance. Covering the C-band in two selectable sub-bands, this LNB incorporates internal filtering to help isolate interfering signals, including potential interference from 5G and WiMAX services. Its low phase noise supports demanding DVB-S2X applications, making it suitable for professional satellite ground stations, teleports, and VSAT networks. Key Features Dual-Band C-Band Reception: Covers 3.40–4.80 GHz across two selectable sub-bands. Integrated RF Filters: Helps provide isolation from interfering signals, including 5G and WiMAX. Low Phase Noise: Designed to meet the requirements of DVB-S2X VSAT profiles. High RF Output Performance: Offers high output compression and third-order intercept performance. Flexible Frequency Reference: Available with an internal reference or an external 10 MHz reference, depending on the selected model. Selectable Band Switching: Uses 13/18 V switching to select between the two frequency bands. High Gain: Provides 60 dB typical gain, with a minimum of 55 dB. Wide Temperature Range: Supports operation and storage from -40°C to +80°C. Flexible Connector Options: Standard N-type connector, with F-type or SMA-type alternatives; an optional separate SMA connector supports DC input and/or external 10 MHz reference input.
