Abstract :
This paper presents the design and hardware implementation of two-stage lumped-element All-Pass Network for group delay engineering. It is designed for 700 MHz band that is assigned for Software Defined Radio and Cognitive Radio applications. Both positive and negative group delay variation is obtained across the band with slope +5.3 ns/GHz and -4.7 ns/GHz. The application of real-time frequency discriminator using high group delay resolution All-Pass Network is established.
