Frequently Asked Questions

What is an ANTI-5G WR75 LNB?

The transmit way by Matrix waveguide provides the LNB with inherent anti-5G IMT @3.5GHz band interference capability.

What is a Strong Rejection-5G WR75 LNB?

This WR75 LNB can directly input 5G IMT@3.5GHz frequency from transmitting waveguide with a 100MHz guard band. At 5G power levels of -30dBm, the LNB output gain (in-band) shows no intermodulation and no saturation. The LNB features built-in high performance out-band rejection passive filters without requiring external mechanical filters.

What is High Gain Low Noise?

High Gain: 63dB (Typical) enables reception of weak intensity signals. Low Noise: 0.8dB (Maximum) guarantees better system C/N value performance.

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 satellite C-Band (3.7-4.2 GHz)

5G Power at LNB Input: -30 dBm (very strong signal - approximately 60-80 dB stronger than typical satellite signals)

LNB Response: No gain, no intermodulation, no saturation - indicating effective filtering that attenuates 5G signals below the LNB's noise floor while preserving amplifier linearity.
