Abstract :
This paper describes the design and implementation of several passive networks, which facilitate controlled 2nd-harmonic impedances at the in-and output of PA´s for mobile applications. Focus is placed on the implementation and performance of series resonators, integrated transformers and tuned center-tapped balun in conventional silicon, high resistivity silicon (HRS) and RF PCB materials.
