Researchers UPCT patented dual channel filter to strengthen and improve communications satellite (27/07/2015)

Integrated RF systems in space satellites will be smaller while robust and versatile thanks to the dual-channel filter patented by the research group in Electromagnetics and Telecommunications at the Polytechnic University of Cartagena (UPCT).

Melcón Professor Alejandro Alvarez, head of the group Electromagnetism, summarizes the new filter that "uses two integrated in the structure, instead of using two or more channel single-channel filters" which saves space and to strengthen the system high power transmissions.

Both advantages are particularly suitable for satellite telecommunications equipment.

"For devices in orbit always seeks to reduce volume and surface and ensure the reliability of the device", argues researcher at the Polytechnic.

The patented filter is also designed for mobile communications or radio and integrated into the RF header.

"The filters pursue minimize noise in signals received and limit the power output to not interfere other systems," explains teacher UPCT.

Another added value of the new filter is its versatility.

"It gives a lot of flexibility to design the desired potency and selectivity to eliminate interference," adds Alvarez Melcón.
