Highly selective lossy dual-band bandstop filter synthesis and design based on predistortion hybrid dual-band elliptic reflection function
This paper demonstrates a new class of highly selective bandstop filter based on cascading two identical lossy hybrid dual-band bandstop filters of low resonator Q factor. Each filter is synthesized based on multi-stage predistortion reflection mode technique. To demonstrate the approach, 4th order...
