Frequently Asked Questions
Q: What is an ANTI-5G WR75 LNB?
A: The transmit way by Matrix waveguide, LNB itself has anti-5G IMT @3.5G Band interference capability.
Q: What is a Strong Rejection-5G WR75 LNB?
A: WR75 LNB directly input 5G IMT@3.5GHz frequency from transmitting waveguide, Guard band=100MHz, 5G Power Level: -30dBm, WR75 LNB output Gain(in-band) no intermodulation, Output Gain no saturation. WR75 LNB itself has strong anti-5G IMT@3.5GHz frequency capability, because with un-linking the mechanical filter outside, WR75 LNB built-in high performance out-band rejection passive filter.
Q: What is High Gain Low Noise?
A: WR75 LNB High Gain: 63dB (Typ.), which can receive week intensity signal; Low Noise: 0.8dB(Max.), which can guarantee system better C/N value.

Interference Scenario Analysis

  • Threat: 5G IMT @ 3.5 GHz (e.g., 3.4-3.8 GHz band).

  • Guard Band: 100 MHz between the 5G band and your satellite C-Band (3.7-4.2 GHz). This is a small but helpful frequency separation.

  • 5G Power at LNB Input: -30 dBm. This is a very strong signal for a receiver input. A typical satellite signal at the LNB input might be -90 to -110 dBm. A -30 dBm interfering signal is ~60-80 dB stronger than the desired signal.

  • LNB Response: No gain, no intermodulation, no saturation. This is the ultimate test of a filter's performance. It means:

    1. The filtering is so effective that the 5G signal is attenuated to a level below the LNB's noise floor, so it contributes no measurable increase in system noise temperature (No ΔG).

    2. The linearity of the LNB's first-stage amplifier (typically a GaAs HEMT) is preserved because the interfering signal is so weak at that point that it never drives the amplifier into its non-linear region (No intermodulation, no saturation).
