Abstract :
New design methodology for truly differential RF and microwave front-ends has been presented in this paper. Baluns are avoided using this design methodology, while achieving differential signaling for high noise immunity. A case study on an ultra-wide band RF front-end in the frequency band 6-9 GHz has been performed using the new design methodology, indicating that both wide bandwidth and high performance can be achieved using this design methodology. A direct comparison between single-ended and differential designs of the RF filter has also been presented in order to verify the correctness of the design methodology.
