PAUXIS PX-D01 C-BAND BAND PASS FILTER+filter

The 3.5GHz frequency band in the 5G frequency band can cause interference to satellite C-band signals. To combat interference, methods such as installing shielding nets, installing filters, moving away from base stations, reducing transmission antenna power, and adjusting transmission antenna direction can be adopted.

We adopt corresponding solutions to meet the different requirements of different users. In situations where military, major satellite engineering, aerospace, and astronomical satellite monitoring must be prioritized, 5G base stations must be constructed strictly in accordance with interference requirements within a safe and coordinated radius to ensure that priority important services are not disrupted. Industry oriented units such as broadcasting stations, banks, securities, hotels, etc., due to their large usage base, it will be normal for their related businesses to be disrupted by 5G. As the next generation communication technology, 5G is the cornerstone of future technological development. It is not possible to choose measures such as not building or moving away from base stations just to avoid some interference problems. Therefore, units using 5G interference must adopt practical and effective methods such as adding anti-interference filters to solve the problem.

In the scenario of receiving signals in the C-band of satellites being interfered by 5G, we are now launching a high-frequency head that supports the anti 5G interference frequency band (for use in weak interference scenarios). The high-frequency head with anti interference has a similar appearance to a regular high-frequency head, with small size, light weight, and easy installation. For different usage scenarios, it is divided into dual local oscillator single output models and dual local oscillator dual output models.

What is the principle of anti 5G interference high-frequency head?

Generally speaking, the satellite receiving system we refer to includes antennas, feed sources, low noise down converters, cables, wiring terminals, satellite receivers, and televisions. The low noise down converter is commonly referred to as a high-frequency head, which is an integrated component of a low noise amplifier and down converter. In the down converter, we filter out 5G interference signals through a bandpass filter and retain effective C-band signals, which can successfully resist 5G interference and ensure the normal reception of satellite signals. Due to its small size, light weight, and low cost, the anti 5G interference high-frequency head is more widely used to combat 5G interference.
