Abstract :
This paper presents a modular low cost approach for building ultra-linear amplifiers for base station telecommunications applications with the use of a low cost stripline serial and parallel combining techniques. The operation of the amplifiers provide "feedforward performance level" with very low complexity assembly and test costs.
