| Challenge | How This LNB Solves It |
|---|---|
| 5G base stations degrade KA-band signal quality |
Built-in high-performance out-band filter withstands -30dBm 5G interference – no intermodulation, no saturation. In-band signal remains clean. |
| Weak KA-band signals in remote areas with insufficient link margin |
63dB typical high gain + ≤1.6dB low noise figure – significantly improves system Carrier-to-Noise ratio (C/N) for reliable weak signal reception. |
| Extreme temperatures cause LO drift |
PLL technology with ±25~±50kHz LO stability – reliable signal lock from -40℃ to +60℃. |
| Lightning strikes during storms damage equipment |
Built-in 4KV~6KV lightning protection – reduces surge damage risk and extends product life. |
| Different KA-band frequency plans across regions |
Input frequency 17.6~26.7GHz customizable with multiple LO options – flexibly adapts to KA-band allocations worldwide. |
| High-Throughput Satellite (HTS) requires tight gain flatness |
Gain flatness ≤2dB p-p per 1000MHz – ensures consistency across multi-carrier signals. |

A: It's an LNB designed with a waveguide path that inherently rejects 3.5GHz-band 5G IMT interference. It features a built-in high-performance out-band passive filter – no external mechanical filter is needed.
Q: How is this different from a standard KA-band LNB?
A: Standard KA-band LNBs may not have 5G filtering capability. The WR42 goes further: even with strong 3.5GHz interference (-30dBm input), output gain shows no intermodulation and no saturation – the in-band signal remains perfectly linear. That's the key differentiator.
Q: What is the real-world value of 63dB high gain?
A: KA-band signals are significantly affected by rain fade. 63dB typical gain compensates for signal loss due to rain, ensuring link availability even in adverse weather conditions.
Q: Is ≤1.6dB noise figure good enough for KA-band?
A: For KA-band, ≤1.6dB noise figure is an excellent level. KA-band operates at much higher frequencies than C-band and Ku-band, presenting greater technical challenges. This specification fully ensures system Carrier-to-Noise ratio.
Q: Can the LO frequency be customized?
A: Yes. The standard version supports multiple LO frequency options including 19.5 / 20.2 / 21.2 GHz. Other frequencies can be customized upon request.
Q: What is the difference between WR42 and WR75 input interfaces?
A: WR42 is the standard waveguide interface for KA-band, with smaller dimensions suitable for the 17.6~26.7 GHz frequency range. WR75 is used for lower frequency Ku-band. The choice depends on the operating frequency band.
Q: How effective is the lightning protection?
A: Built-in 4KV~6KV surge protection effectively withstands lightning-induced overvoltage, reducing equipment damage risk during storms – ideal for unattended outdoor installations.
