The output of the current generation of digital processors, used on commercial satellite missions, is either at baseband, or a low IF. This signal must then be up-converted to the operating frequency of the spacecraft, such as C, Ku or Ka-band. The need for these up-converters significantly increases the cost per output of digitally processed payloads. This study has investigated if/how conventional frequency up-converters could be replaced with an Ultra-highspeed DAC’s

The Ka-band feed positioner enables cross polarisation to be optimised, while
the terminal is transmitting. For 1.8 and larger offset Ka-band reflectors, this
saves a lot of installation time, because the AzEl don’t need adjustment. Having
set the AzEl for receive cross polarisation, the transmit will be a few millimetres
away, and this can be achieved in a few seconds by moving the feed.
For inclined tracking, the motorised feed saves cost, freight, installation time
and running costs compared to a AzEl solution. The feed can be fitted
retrospectively to an existing antenna. It is positioned by connection to TLE.

Waveguide harnesses for multi-beam satellite applications are contributing a substantial portion of the overall payload mass budget.

Among all antenna payload solutions suitable to support reconfigurable and flexible broadband satellite communication missions, DRA antenna systems represent the typical candidates to fulfill these requirements.
Unfortunately, periodic DRA antenna solutions are characterized by different drawbacks, mainly related to the very large array aperture dimensions needed to obtain narrow high-gain spot beams, with as consequence very high number of active radiating elements, high system complexity, high weight, difficulties in accommodation and high manufacturing costs.
Another key point for future satellite telecommunication missions is to consider antenna systems able to operate simultaneously at both receive and transmit bands using the same antenna aperture.
The transmit/receive DRA antenna characterized by the same aperture for satellite applications presents many difficulties at higher frequency as the Ka Band, due to the operative frequency band considering a frequency ratio 1.5 between transmit and receive. In this respect, the selections of the adequate radiating element inter-spacing and the antenna aperture size have to consider both transmit and receive performances.
A very interesting antenna solution potentially suitable to overcome all these drawbacks is represented by an Imaging antenna architecture fed by two small active phased arrays, one for TX and one for RX.
Moreover, in order to minimize the number of radiating elements, satisfying pattern requirements in terms of sidelobe and isolation levels, aperiodic/sparse array configurations have been considered to feed the Imaging antenna system.
