Multipactor

The multipactor discharge happens when a bunch of free electrons come into resonance with the electric field and grows exponentially due to the interaction with the walls of the device, producing an avalanche of electrons followed by the corresponding breakdown.

We have high-vacuum facilities and cutting-edge radiofrequency equipment to carry out multipactor tests for both flight models and R&D prototypes. Thanks to our wide range of amplifiers we cover frequencies from UHF to Q band.

In addition, we have developed a large number of multipactor detection methods (both local and global), which we use to achieve the best levels of sensitivity detection and diagnostic in the multipactor discharge.
