The SMW Ku-Band Q-PLL (Phase-Locked Loop) LNB, Type J is a high-performance, low-noise block downconverter designed for reliable and stable satellite signal reception. Engineered by Seatel, this model is built for professional and demanding applications where signal integrity and consistency are paramount.
Its advanced Q-PLL technology provides exceptional frequency stability, minimizing phase noise and drift for superior picture and data quality. This LNB is optimized for use with a 1.0-meter (Single) offset satellite antenna, making it an ideal choice for VSAT, maritime, enterprise, or high-end residential satellite communication systems operating in the 10700 to 12750 MHz Ku-band downlink range.
Key Features & Specifications:
- High-Performance Technology: Features a Phase-Locked Loop (PLL) oscillator for ultra-stable local frequency, crucial for digital data, HDTV, and broadband services.
- Low Noise Figure: Ensures excellent signal sensitivity and clarity, even under marginal signal conditions.
- Wide Frequency Range: Covers the full 10700 – 12750 MHz Ku-band spectrum.
- Type J (Single Output): Designed for a single coaxial cable run to an IRD (Integrated Receiver/Decoder) or satellite modem.
- Robust Construction: Built for durability and long-term reliability in various environmental conditions.
- Precise Compatibility: Optimized for use with a standard 1.0-meter offset satellite dish.
Applications:
- Maritime & Offshore Satellite Communications (e.g., on Seatel antenna systems)
- Enterprise VSAT Networks
- High-Reliability SCPC/MCPC Data Links
- Professional Broadcast Uplink/Downlink Feeds
- High-End Residential Satellite TV (where local oscillator stability is critical)
