Demonstrate 5Gbps+ downlink from a 10-Watt 3U radio transmitter.


Test own GaN-on-Diamond transmitter technology with a flight-proven software defined radio (SDR) in a compact form factor. Demonstrate the transmitter’s capability to handle more than five gigabits per second (5Gbps+) downlink speeds from a 10-Watt 3U radio transmitter. Simulation and ground-based lab tests have proven that the Akash GaN Transmitter is capable of transmitting data rates as high as 14 Gbps.

The Ka-band parabolic antenna has a 3 dB beamwidth of 2.2degrees and a gain of 36.2 dBi. The Akash GaN Transmitter will downlinkpre-configured test data over a single 1.2 GHz bandwidth channel in Ka-band (19.0 -20.2 GHz) to a 13.2 meter ES in Dongara, Western Australia. MCNAIR’s S-band TT&C SDR will receive telecommands from and transmit telemetry to a3.7mKSAT ES located in Svalbard.
