In 2018, Callisto was awarded an ESA's Technology Research Program contract to study and develop an RF sampling demonstrator.
The demonstrator has been designed to operate in ESA Rx frequency bands: S, X, K and Ka. At the end of 2019, after the completion of the design phase, the demonstrator has been developed and tested in S & X-band.
Factory acceptance tests are validated by ESA, which confirm the expected performance over 250MHz bandwidth.
Next step is to test this demonstrator in an operational environment.
