Abstract
A large-signal characterization for a travelling wave amplifier (TWA) is presented based on measurements with a non-linear vector network analyzer. The TWA is a four stage CPW design fabricated in a 0.15 ¿m GaAs HEMT process. The measurement results are compared with simulations in the frequency domain and in the power domain up to the fifth harmonic. Over all a good agreement has been achieved. The model for the transistors, implemented as user-defined model in Agilent ADS, is suitable for large signal designs, especially for high output voltage swings required for drivers of optical modulators.
