Reliability Advantages Of Modular Solid State Power Amplifiers Compared To Traveling Wave Tube Amplifiers
By Stephen Turner, VP of Engineering, Paradise Datacom
Amplifier manufacturers have long compared the advantages and disadvantages of solid state power amplifiers (SSPAs) and traveling wave tube amplifiers (TWTAs). Every few years, there is typically a technology advance that gives a slight advantage to one technology over the other. This paper shows how the modular design of SSPAs can provide dramatically higher levels of system reliability than TWTAs.
