Reconfigurable phaser using gain-loss C-sections for radio analog signal processing (R-ASP)

Some emerging applications of R-ASP require the radio systems to adapt to dynamic environments. This cannot be achieved using phasers with fixed group delay profiles. Therefore, we introduce here a gain-loss loaded C-section phaser featuring real-time tunability, or reconfigurability, in group delay. This phaser exhibits an all-pass response all the way across its tuning range thanks to a paired and equalized gain-loss C-section unit. A numerical example is provided, where reconfigurability is achieved by tuning the gain-loss pair of the different gain-loss C-section units of the phaser.
