About
The WiRan X-Band Diplexer DXB is a communication component designed to provide full-duplex communication capabilities for data transmission and dedicated swarm radiocommunication within the X-band frequency range. It operates in the 7145-8500 MHz band, which covers a significant portion of the Earth Observation frequency spectrum. This diplexer is compliant with the CubeSat nanosatellite standard, making it suitable for small satellite missions. Its development was supervised by the European Space Agency, indicating a focus on space-grade quality and reliability. Key features include high power handling levels, a compact design with low height and volume to conserve space within satellites, and full compatibility with WiRan’s currently developed X-Band antenna. The DXB also boasts isolation levels comparable to waveguide components, exceeding 80dB, ensuring efficient signal separation. Technical specifications and S-parameters are available upon request, and the manufacturer offers preordering inquiries.
