SOLID STATE POWER AMPLIFIER (SSPA)
The Solid State Power Amplifier (SSPA) product line was designed for use in the most demanding applications, including Airborne, Missile, Radars and Communications. Out SSPAs design is based on cutting edge GaN technology and various types of architectures. As a result, these SSPAs provide high efficiency, high power levels and small footprint. Our SSPAs are an alternatives to applications that currently are using Traveling Wave Tube (TWT) Amplifiers. All SSPAs are designed using the Power Summation concept (see Fig.1) which provides a graceful degradation capability not found in TWTs and critical to mission completion.
The SSPA product line supports both X and KU Band applications with bandwidth of 10% typically, offering peak power outputs up to 400 Watts. Successful SSPA designs have utilized Gallium Arsenide or Gallium Nitride power devices, depending upon which was better suited for the application. The flexibility of the SSPA design provides the ability to extend to adjacent frequency bands requiring only a short development time at a very low risk.
