Direct conversion system advantages include increased flexibility, reduced complexity, weight and power consumption. Direct conversion to and from Ka-band frequencies is now possible with good performance.

This paper highlights advances in wide bandwidth data converters. Ka-band direct conversion results from the latest 25GHz bandwidth DAC, EV12DD700, and also a direct down conversion ADC module EV12PS640, with analog bandwidth of greater than 20GHz.

Applications in Radar, Radio Astronomy, Telecomms and Electronic Warfare will be discussed.


EV12DD700 development has been co-funded by Interstellar EU project, from Horizon 2020 Space programme under grant agreement N° 730165.
