Miniaturized Ka-Band radio for small satellites
Radiosat
In its own small way, 1.5 U and 1 kg, a Ka-band radio is integrated with a DVB-S2 modem, overall characterized by low power consumption. The usage of this frequency band ensures data rates greater than 20 Mbps, in a less congested spectrum environment. Signals are processed by the modem, which provides Variable and Adaptive Coding and Modulation (VCM, ACM) capabilities.
The radio allows the separate management of the receiver and the transmitter.
