Optimized for Ku-Band High-Band Reception – Supporting Both Linear and Circular Polarization

Focused Ku-Band High-Band Reception Solution

For users who only need to receive the Ku-band high-band (11.7-12.75GHz), a focused, efficient, and highly compatible LNB is the ideal choice. The Ku-Band Single LO LNBF ST-K11WS is exactly that solution.

This product features a fixed single local oscillator frequency of 10.75GHz with an integrated feedhorn, downconverting the incoming Ku-band high-band signal to a 950-2000MHz L-band output. What makes it truly versatile is its support for both linear polarization (Vertical/Horizontal) and circular polarization (LHCP/RHCP) , adapting to different satellite polarization standards worldwide.

Key Advantages:

• Focused High-Band Coverage – 11.7-12.75GHz input frequency, precisely covering Ku-band high-band

• Single LO Design – Fixed 10.75GHz local oscillator for simple and stable circuitry

• Dual-Polarization Support – Compatible with both linear (V/H) and circular (LHCP/RHCP) polarization

Q: What is a Single LO LNBF?

A: A Single LO LNBF uses a fixed local oscillator frequency (10.75GHz) to process incoming signals. Unlike dual-band universal LNBs, it focuses specifically on the Ku-band high-band (11.7-12.75GHz), offering simpler circuitry and better price-to-performance ratio.

Q: What polarization types does this LNB support?

A: Supports two polarization types:

• Linear: Vertical / Horizontal

• Circular: LHCP (Left-Hand Circular) / RHCP (Right-Hand Circular)

Polarization switching is controlled by the receiver's 13V/18V voltage signals.

Q: What is the real-world benefit of the 0.7dB noise figure?

A: Lower noise figure means the LNB generates less self-noise. With 0.7dB (Typ.) , you get clear, pixelation-free pictures even in weak signal environments – especially valuable for Ku-band high-band reception.

Q: What is the advantage of the integrated feedhorn design?

A: Traditional LNBs require a separate feedhorn purchase and assembly, which can be cumbersome and may affect performance if not properly matched. The integrated feedhorn design eliminates extra components, simplifies installation, and ensures optimal waveguide matching performance.

Q: What is the output frequency range of this LNB?

A: The output frequency range is 950~2000 MHz, covering the full L-band and compatible with the vast majority of satellite receivers on the market.

Q: What is the operating temperature range?

A: -30℃ to +60℃. This covers most climate conditions – from cold winters to hot summers.
