X Band Low Pass Filter: Let our RF engineers help you configure one.

AWG Tech has been supplying X Band low pass filter to many companies worldwide. An X-Band low pass filter is designed to have a cut-off frequency anywhere in the range from 8GHz to 12 GHz.

There are many systems that uses the X band. These include:

• X Band satellite communications
• X Band Radar system
• Terrestrial microwave radio for communications and networking
• Space communications like DSN (Deep Space Networks)
• Amateur radio in the range from 10.0GHz to 10.5 GHz.

Getting an X Band Low Pass Filter configured for your application is easy. Just complete the product enquiry form below with details about the required cut-off frequency and rejection. Our experienced RF engineers would be glad too assist you if you have any difficulties in deciding the required specifications.

The Main Characteristics of X-Band Frequencies in Satellite Communication

The X-band frequency, or known to some as the Super High Frequency (SHF) signals, is a sub-region in the microwave radio region of the electromagnetic spectrum that is in the range of 8 to 12 GHz and has a wavelength range of 2.5 to 3.75cm. In some cases, however, like in communications engineering, the frequency range of the X-band is set to approximately 7 to 11.2 GHz. In radar engineering, the frequency, according to the IEEE, is set to the average frequency range (8 to 12 GHz).

Asides from its usual utilization in satellite systems, the X-band can also serve a function in RF filters. An X Band low pass filter, for example, functions by allowing low frequency signals to pass through it and blocks every high frequency signal that may enter. In practical applications, say in radars, these low pass filters prevent high frequency signals from entering; plus with the X-band frequency, the images on the radar becomes clearer and allows viewing of high resolution images.

Main Characteristics of the X-Band Frequency in Satellite Communications

Here are some of the main characteristics of the X-band frequency when used in satellite communications:

Strong Resistance to Rain: X-band is a type of frequency band that is below any frequencies that may be severely affected by heavy rains. Thus, the X-band offers an amazingly wonderful protection when it comes to rain unlike Ku and Ka Bands. This also permits for extremely high link availability, possibly as high as 99.9%.

>4⁰ of Separation between Satellites: X-band satellites usually have at least 4⁰ of separation between satellites. Therefore, there is a lesser chance of adjacent satellite interference (ASI) and high power density carriers are permitted.

Terminal Size vs Data Rates: As with any other satellite communication connection, the link data rate can be attained with a terminal that’s dependent on the gain of the antenna. Antenna gain then rises with the square ratio of aperture width to wavelength.

In terms of data rates, the X-band frequency provides data rates that are much higher than with other frequency bands, such as UHF, L-band or C-band. The attained data rate will most likely be close with the data rates that the Ku-Band will provide. However, the exact value of data rate will hugely depend on other link parameters (satellite power and link margin are some examples).

Therefore, both terminal size and data rate offers an excellent compromise while maintaining its strong protection against the rain.

Remote and Maritime Coverage: X-band frequencies are able to provide support to users in remote areas with little to zero infrastructures and in mid-ocean locations away from land and shipping lanes. This is due to the fact that X-band satellites also have a global beam that provides coverage of the entire planet that’s visible from the satellite.

Overall, the main functionality of these X-band frequencies in RF filters, such as an X-Band Low Pass Filter and in satellite communications, provides users a clearer reception of the transmission even if in heavy rain showers.
