Product Description

WR42 Ka-Band LNB for FSS/VSAT Systems

17.6-26.7GHz, High Gain, Low Noise

Product Overview

The SETON Anti-5G Ka-Band WR42 LNB is a high-performance Low Noise Block downconverter engineered for KA-BAND FSS and VSAT systems. Featuring customizable frequency ranges and superior signal reception capabilities, it delivers reliable performance in environments with adjacent 5G interference.

Key Technical Advantages

Powerful Anti-5G Interference Capability

Built-in High-Performance Rejection Filter: Unlike traditional solutions that rely on external mechanical filters, the SETON WR42 LNB integrates a high-performance out-band rejection passive filter internally. This design fundamentally eliminates the insertion loss and bulkiness associated with external filters, achieving highly efficient, all-in-one interference suppression.
Specifically Targets 3.5GHz Adjacent Interference: Optimized for the 3.5GHz 5G IMT band, the built-in filter features a sharp rejection skirt. Even under harsh conditions with an interferer power level as high as -30dBm and a guard band as narrow as 100MHz, it effectively blocks interference from entering the LNB. This ensures the internal amplification circuitry remains unsaturated and free from intermodulation distortion.
Direct Waveguide Input: Signals are input directly via the WR42 waveguide flange, minimizing path loss and ensuring interference is effectively filtered before reaching any active circuitry.

High Gain & Low Noise Figure

Ultra-High Gain (Typ. 63dB): With a typical gain of 63dB, the SETON LNB can sufficiently amplify weak satellite signals, ensuring adequate signal strength for the demodulator. This is particularly crucial for regions with high rain attenuation and low elevation angle reception.
Ultra-Low Noise Figure (Max. 0.8dB): The industry-leading maximum noise figure of just 0.8dB minimizes the noise added by the LNB itself, guaranteeing an excellent system Carrier-to-Noise (C/N) ratio. This translates to more stable connections and higher data throughput for end-users.

Applications

Satellite earth stations affected by 5G base station interference (especially 3.5GHz band)
Professional satellite communication systems requiring high reliability and stability
Scenarios with space constraints where external filters are impractical

Frequently Asked Questions

What is an ANTI-5G KA WR42 LNB?

Features matrix waveguide transmission with built-in anti-5G IMT @3.5GHz band interference capability.

What is a Strong Rejection-5G WR42 LNB?

Directly inputs 5G IMT@3.5GHz frequency from transmitting waveguide with guard band=100MHz and 5G Power Level: -30dBm. Maintains output gain without intermodulation or saturation due to built-in high-performance out-band rejection passive filter.

What is High Gain Low Noise?

High Gain: 63dB (Typ.) for receiving weak intensity signals; Low Noise: 0.8dB(Max.) to guarantee better system C/N value.
