A comparison between 4-bit fixed and reconfigurable microwave discriminators for frequency identification

This paper presents a comparison between fixed and reconfigurable 4-bit microwave discriminators. The fixed discriminator is implemented by using multi-band-stop filters to define bits used for frequency identification. The reconfigurable discriminator is implemented by using delay lines and two SPQT switches. Both designs operate at L and S bands, a comparison between both devices is provided, including simulated and measured responses for both designs.Grant numbers : This work was supported by the Spanish Ministry of Economy and Competitiveness projects PIB2010BZ-00585 (NANOWAVE).
