Linearized transponder technology for satellite communications. I - Linearizer circuit development and experimental characterization
Abstract
The operational principles and design of transmission and reflection types of predistortion diode linearizers are presented. The performance of four different linearized traveling wave tubes (LTWTs) in multicarrier operation is evaluated experimentally, and the measured performance of a soft-limited LTWT is presented. Experimental results on linearization at an intermediate frequency of a transponder are also given.
