• Reliable, efficient, lower power consumption
• Still issues with Size and Weight
• Gallium Nitride (GaN) SSPA’s
• Availability started within last 10 years
• More efficient, smaller , lighter and even lower power consumption.
• Issues with non-linearity

WHY INNOVATE?

• Satellites are going through a complete revolution
