GANSAT project will demonstrate that GaN-based SSPA will be able to provide high power at Ka band. This will be achieved by exploiting the recent development in GaN technologies, high-efficiency power amplifier design techniques, spatial power combining and active array antenna technologies.
It is expected that a power output of several hundreds of Watts at Ka band will be achievable by using the approach to be taken in GaNSAT. This will be a significant step beyond the state of the art, and will open the door for GaN-based SSPA into various space applications such as satellite communications, DBS and SAR. Due to high power density of GaN devices, the system will have advantages of compact size, low mass and low cost, suitable for low-cost small satellites where the physical size, mass, power consumption and cost pose serious restrictions. The GaN amplifier will also be useful applications into large satellites and enable significant reduction in size, mass and cost.
GANSAT Objectives and approach
As was expressed above the project will be dealing mostly with the design of a high efficient Ka-band GaN RF front-end. In order to achieve this main goal the project addresses significant challenges in high frequency high powersatellite radio transceivers from several different angles, as follows:
- Enhanced robustness and functionality of radio transceivers at Ka-band;
- Space qualification of GaN MMIC;
- Packaging of GaN MMIC;
- High-efficiency high-power multi-beam active Tx/Rx antenna;
- High-efficiency high-linearity PA;
- New linearization technique.
