5 Advantages of GaN Solid State Pulsed Power Amplifiers Over TWT Amplifiers

by Jaymie Murray 16. March 2015 10:25

Traveling Wave Tube (TWT) amplifier technology has several inherent limitations that are easily overcome by using the kind of state-of-the-art GaN Solid State Pulsed Power Amplifiers designed and manufactured by API Technologies. The benefits of utilizing GaN transistor technology over TWT include longer lifespan, decreased risk associated with infant mortality after long storage periods, and the elimination of multiple single point failure sources. 


5 Advantages of GaN Solid State Pulsed Power Amplifiers Over TWT Amplifiers Your website Remove concern about TWT damage at turn-on after extended storage periods Eliminate a system’s finite life due to cathode exhaustion in the TWT To minimize risk of damage after prolonged storage, an 8-24 hour heater burn-in is recommended before cathode voltage is applied to TWT amplifiers. SSPA amps do not have this risk and can be immediately turned on after extended storage periods. Although there are steps that can be taken to extend cathode life, TWTs still have a finite operating lifetime. By using a GaN SSPA instead, cathode exhaustion can be eliminated altogether, significantly extending the system’s operating life.Get distributed final stage health monitoring & early failure warning while maintaining system operational integrity Eliminate multiple single point failure sources in the TWT SSPA uses parallel combined transistors that provide a soft fail configuration. Parallel power sources in the SSPA provide the opportunity to monitor amplifier health at multiple power stages. TWT relies on energy transfer from the electron beam into the RF signal traveling along a helix wire. All components in the tube are potential single point hard failure sources.
