High-Efficiency SSPA Technology
• AstroComm has designed hyper-efficient SSPA with PAE > 75%
- High fidelity simulations indicate PAE of 75.9%
• Next steps:
- Develop a prototype
- Produce a portfolio of 1W & 10W SSPA’s in S, X, Ku & Ka frequency bands
Solid State Power Amplifiers (SSPA) are the core of transceivers/transmitters in satellites and remote mobile data collectors
AstroComm has invented a technique to increase SSPA Power Added Efficiency (PAE) to >45%, which will greatly improve the transmission of large data. Continued R&D indicate PAE could be raised to beyond 70%
These high-efficiency SSPAs have multiple uses and is a timely invention given the proliferation of small, low cost satellites and remote mobile communication applications. Advent of 5G Technology opens up a new terrestrial communication opportunity
Initial prototype has already been developed and further improvement continues.
AstroComm looking to work with potential Users to custom design high efficiency SSPAs to meet specific requirements
vs. Industry Efforts
Progress being made in the industry through improvements in GaN materials.
Relatively expensive solution
Signal processing identified as a technique for enhancement in PAE
Design developed to produce SSPA with PAE > 45%
Applicable to GaA & GaN materials
Can be produced in high volume at low cost
Ideally suited for application on cubesats and nanosats
budgeted < $30K for transceivers and < $10K for SSPAs.
Produced an S-Band 1W prototype with around 40% PAE.
Provisional patents filed; final patent will combine these and
subsequent SSPA inventions.
