The Akash systems Ka/S Cubesat Radio is a software defined radio (SDR) operating in S-band frequency suitable for smallsats. The system allows inflight modulation adjustments.

Gallium Nitride (GaN)-on-Diamond MMIC Power Amplifier, a proprietary technology of Akash systems, is used in the SDR to enhance the thermal and RF performance. The amplifiers are suggested by the supplier for missions with requirements for high efficiency, high data rates, and low SWAP.
